•SIGTRAN implements the SCTP protocol, which is a peer to TCP and UDP, but has

improvements. They also defined numerous adaptation layers that maintain MTP2 and/or

MTP3 functionality from the SS7 stack.

•IETF is an open standards organization supported by ANSI, ITU and ISO and is tasked to

provide standards for all aspects of Internet communications.

For further information on SIGTRAN, refer to RFC 4960


The SIGTRAN family of protocols used by the IPSG includes:

•MTP2 User Peer-to-Peer Adaptation Layer (M2PA)

•MTP3 User Adaptation Layer (M3UA)

•Stream Control Transmission Protocol (SCTP)

•The following features must be turned on for 1 Million TPS:

• HIPR2 High Rate Mode

• 1M System TPS


SS7 over IP requires that a path across the network must be defined in the STP that tells

the network where to deliver the packet.

An association is a path across a network. An association path is defined by the two

endpoints that it connects.

Delivery process:

•An MSC generates an SS7 MSU and sends it to the STP.

•MSUs are routed through the STP (based on the DPC) to the SIGTRAN card.

•SIGTRAN places the SS7 messages in the Data field, builds the packet header and then

sends the packet out the Ethernet port.

•The packet traverses the IP network.

•The packet is received at the destination STP.

•The SIGTRAN card extracts the SS7 MSU from the Data Field and routes it (based on

DPC) to the next linkset.

•The MSU is delivered to the MSC.


The Eagle adapts an SS7 MSU to transport it across Ethernet and IP using a SIGTRAN

Modules. E5 Ethernet Modules are:

• E5-ENET – Implements thirty-two (32) MTP3 links (A, A1, to A15 and B, B1, to B15) to

up to two physical ports at up to 5000 transactions per second. up to 6500 TPS while

running the IPSG application if the E5-ENET-B IPSG High Throughput feature is

turned on.

E5-ENET-B – Implements thirty-two (32) MTP3 links (A, A1, to A15 and B, B1, to B15)

to up to two physical ports at up to 9500 transactions per second.

•Delivering MSUs to Ethernet

• MSUs are delivered to one of the SS7 signaling link type application cards.

• The SS& link card sends the message to the SIGTRAN card via the IMT bus into an

SS7 MTP3 layer on the SIGTRAN module.

• SIGTRAN protocols place the MSUs into Ethernet packets and deliver them to Ethernet

networks.

• Each SIGTRAN module can use up to two independent Ethernet networks for reliability.

• Ethernet networks deliver MSUs to the distant end IP endpoints.


Each SIGTRAN card has two physical interfaces (Ethernet port A and Ethernet port B)

IP addresses are assigned to the SIGTRAN (E5-ENET/E5-ENET-B) card, not the STP.

All IP addresses related to the network for port A must belong to a different network than

the addresses for port B. (Using port B is optional).

Notice that the SIGTRAN card port must have the same network address as the router for

that network.


•E5-ENET or E5-ENET-B cards must communicate to Ethernet Switches (one per physical

interface).

•The local Ethernet network delivers packets to a Wide Area Network (WAN) which

delivers the packets to a distant Ethernet Local network.

•The distant IP Endpoint might be another STP or it might be some other IP signaling

device.

•SIGTRAN treats each MTP3 link as a separate application (program).

•The logical path from one MTP3 link at the near end to one MTP3 link (or its equivalent) is

called an “association”


NOTE: IP Signaling Gateway requires EAGLE Release 38.0.1 and above.


SIGTRAN Adaptation Layers

•The Data Chunk carries the Adaptation layer. The Chunk will consist of a SIGTRAN

management message or an actual MSU.

SIGTRAN protocols:

•M2PA – MTP2 Peer-to-Peer Adaptation layer

•M3UA – MTP3 User Adaptation layer

NOTE: SUA (SCCP User Adaptation) layer is NOT supported in IPSG.


•Application Servers are databases that respond to transaction based queries.

•The Media Gateway Controller receives call setup and call tear-down messages from the

EAGLE STP IPSG.


Application Servers (AS)

Implement Advanced Services

• Similar to SCPs but with many enhancements

• Unlike SCPs, Application Servers can initiate transactions

• Answer queries from SSPs

• Prepaid, postpaid, and automatic billing

• Multimedia services

• Voice over IP management and tracking

• Short Message Services

An Application Server has one Point Code and Link Set

Application Server Processes (ASPs)

• One AS can use multiple ASPs to support reliability and increased throughput through

load sharing.

• Eagle STP can be provisioned to load share among ASPs assigned to the same AS.

• Each ASP has one association. Each association connects to one MTP3 link (A, A1,

A2, etc). Each MTP3 link is one slc in the Link Set.

• Load sharing among MTP3 links is controlled by slc.


•SS7 over IP plays an important role in voice over Packet Network telephony.

•Media Gateway Controller (MGC) (Softswitch) provides the Media Gateway with the

directions that it requires to complete a call

• Receives call setup requests from SS7 packets across an IP network

• Translates each request into all of the commands an MG needs to complete the call

• One MGC can direct many MGs.

•

•Media Gateway (MG) converts among different voice protocols.


Converged Network Protocols

The above slide demonstrates SS7 messages that are routed through the STP through A,

B, C, and D links

•SS7 Messages are delivered to the next STP

•SS7 Messages are delivered to an Application Server

•SS7 Messages are delivered to a MGC


Module 1 Review

1. What standards body formed the SIGTRAN Working Group? __________

2. Name three SIGTRAN applications on the EAGLE: ____________________

3. IPSG supports both ANSI and ITU implementations on the same card.

True False

4. What IPSG endpoints respond to the transaction based queries?

________________________and __________________________

5. Which SIGTRAN implementation supports A, B, C, and D link sets?

______________

6. IPSG connects the STP to Application Servers. True False

7. Which node converts SS7 messages from SS7 to SIGTRAN?

____________

8. SIGTRAN cards provide how many Ethernet ports that connect the STP to

the Local Area Network? _________


•SIGTRAN uses SCTP as a transport protocol.

•RFC 4960 describes the SCTP Protocol

•SCTP connections are defined (provisioned) as an “Association” between two endpoints.

•SCTP connections support multi-homing.

•Each connection can have multiple “Streams”.

•Each stream can support multiple data chunks.


•ent-assoc always builds four streams

•Stream 0 is used for Management Messages

• Made up of two bi-directional streams

•Stream 1 is used for processing MSU traffic

• Made up of two b-directional streams

•Some devices support only two streams.

•The association can be modified to work with devices such as application servers..

•chg-assoc : aname = <name> : istrms=1 : ostrms=1


Each association has a unique name.

• All other commands reference the association by the association name.


TUPLE – parameters that define the IP addresses and SCTP ports to use for the local and

remote hosts.

1. Lhost (Local Host) – Hostname that represents the IP address of the local

Ethernet port on the SIGTRAN card (See IP-Host command)

2. Lport (Local Port) – SCTP port (any number greater than 10000). Tekelec

standard = SIGTRAN card slot location x 10

3. Rhost (Remote Host) - Host name that represents the IP address of the remote

host.

4. Rport (Remote Port) - SCTP port for the remote host application.

5. Alhost (Alternate Local Host) – An alternate local IP address that can be used for

this connection. The Alternate Local Host parameter (if defined) is used to

implement multi-homing. The Local Host and the Alternate Local Host must be

defined as different Ethernet Ports of the same SIGTRAN card.

6. Arhost (Alternate Remote Host) – An alternate remote name that represents the

IP address of the alternate remote host used in multi-homing.


•Multi-homing provides an alternate communications path in case the primary path fails.

•When SCTP initializes a connection, it will offer the local host and the alternate local host

(if provisioned) a usable IP address.

•The response from the remote end will list its local host and alternate local host as usable

IP addresses.

•If the Primary path fails, the SIGTRAN card will switch to the port for the alternate local

host and transmit packets to the alternate IP address for the remote.

•This slide depicts the recommended order of data entry into the EAGLE 5 STP.

•Assuming that initial EAGLE 5 Signaling Gateway configuration has been performed, the following

steps for IPSG M2PA configuration are:

• SS7 configuration Part A

• Add SIGTRAN cards – ent-card

• Add Destination Point Codes - ent-dstn

• Add linksets - ent-ls

• IP configuration

• Define IP and Ethernet parameters for each port – chg-ip-lnk

• Assign host names to IP addresses – ent-ip-host

• Set default router, DNS servers (if used) and search order – chg-ip-card

• Define a second router when both Ethernet ports on a card are used – ent-ip-rte

• Configure SCTP associations from the local host and port to the remote host and port

– ent-assoc

• SS7 configuration Part B

• Add signaling links – ent-slk

• Add routes – ent-rte

• SS7 and SIGTRAN activation

• Put the SIGTRAN cards into service - alw-card

• Put the signaling links into service – act-slk

• Change the associations to open and allow traffic on the associations – chg-assoc


Parameters used are:

:appl- the application running on this card

:loc-the physical card slot location of the card

:type-the type of card being entered

IPSG supports protocols M2PA and M3UA, but not SUA.

Fill in the command parameters for the example network

ent-card:type=______________:appl=______________:loc=______________



:dpc – the destination point code in the form of ANSI, ITU-I, or ITU-N

:bei – broadcast exception indicator, determines if network management messages are

transmitted to the point code, values of yes, or no

yes indicates messages are not broadcast

no indicates messages are broadcast

:clli – common language location identifier – indicates physical location of signaling

point

Up to 2,800 destinations may be provisioned on the EAGLE


ent-dstn:dpc=_______________:clli=________________:bei=__________



:apc- the point code at the far end of the linkset

:lsn- linkset name

:lst-linkset type, m2pa uses B,C &D linkset types

m3ua uses A linkset type only

:adapter – m2pa or m3ua

:ipsg=yes for IPSG linksets

slktps – the number of transactions per second (TPS) that is assigned to each IPSG

signaling link that will be in the linkset, from 100 to 5,000.

lsusealm – specifies the percent of the linkset TPS at which an alarm is generated to

indicate that the actual linkset TPS is approaching the configured iptps value for the linkset

slkusealm – specifies the percent of the link “fair share” TPS at which an alarm is

generated to indicate that the actual link TPS is approaching the link’s fair share of its

linksets configured TPS (iptps). The fair share of the linkset TPS for a link is the configured

linkset TPS divided by the number of in-service links in a linkset.


chg-ls:lsn=_______________:lst=_____:apc=_______________________

:adapter=________________:ipsg=__yes_____


•Alarm 0116, slkusealm trips when the transactions across at least one link in a link set

exceed the signaling link fair share value.

•The signaling link fair share is the sltps times the number of links in a link set.

Let’s take an example where we have 4 links in a link set. It does not matter whether the

links are on the same card or not. The slktps is set to 1000, lsusalm is set to 80%, the

slkusealm is set to 60%

Example 1: (First row on table above) All links are in service. The total Link Set tps=

1000tps/slk * 4 slks= 4000 tps. The link set will trip alarm 0115 if the total tps in the link set

exceeds 4000tps/ls * 80% = 3200 tps. The slk fare share is 4000 tps/ls div 4 links = 1000

tps. The slkusalm will trip at 60% of the fare share (1000tps/slk * 60% = 600 tps.)

Example 2: (Second row on table above): One link is out of service. The lsusealm still trips

at 3200 tps, but now the slkusealm doesn’t trip until 800 tps.

In this way, as two links go out of service, the lsusealm is still 3200 tps, but now the

slkUsealm doesn’t trip until 1200 tps.

With three links out, lsusealm is still 3200 tps, but the slkUsealm is way up at 2400 tps.

43


ent-assoc:aname=_______________:lhost=_____________________:adapter=_______

:lport=___________:rhost=_______________:rport=_______________

:alhost=____________


•The chg-assoc command can be used to provide the alternate path to fail over to if the

primary path fails

•The path is from alhost to rhost.

•rhosttype = alternate says that the rhost this time is an alternate host, not a primary host.

•rhostval can have any one of two values

relaxed – The remote host can be negotiated when the association is established. If the

other end offers a new rhost, use that one. If you set this mode, then rhost and

rhosttype are both optional. The drawback to this mode is that if the primary path fails

and the association goes down, it cannot come back up on the alternate path.

match – (Sometimes known as strict mode.) When the association comes up, the other

end must offer this host IP address as the alternate. If it does not the link cannot come

up. The other end must be RFC 4666 compliant for this mode to work. The advantage

of this mode is that if the primary path fails, the association can go down and come up

on the alternate path. If the primary path fails, the alternate then becomes primary for

all practical purposes.



:loc – location of link Interface card supporting the signaling link

:lsn – name of the linkset the signaling link is a part of

:link – signaling link port of the signaling link card

:slc – signaling link code – a unique value for a each link in a linkset

Learning Activity 1: Provisioning IPSG M2PA

1. Login to your assigned STP

Login:uid=eagle

(password) eagle

2. We must enter the card, create the required destination and change a linkset.

3. Enter the SIGTRAN card

Course Notes


•This slide depicts the additional data entry necessary for M3UA configuration.

• IP configuration

• Enter a link set – ent-ls

• Enter a network appearance in the network appearance table – ent-na

• Enable the Bearer Independent Call Control feature – enable-ctrl-feat

•SS7 and SIGTRAN activation

• Put the SIGTRAN cards into service - alw-card

• Put the signaling links into service – act-slk

• Change the associations to open and allow traffic on the associations – chg-assoc


lsn- Linkset name

apc- The DPC of the Application Server (ASPs do not have Point Codes)

ipsg=yes

slktps= (See M2PA slktps)

lsusealm= (See M2PA lsusealm)

adapter=m3ua

rcontext= This is essentially an optional security measure for communicating with

Application Servers. If an Application Server is configured with a routing context

number, then the Link Set must be provisioned with the same exact number (from 1 to

4294967295).

It acts as a filter, filtering out ASP active and Inactive messages when the numbers

don’t match. It locks in DPC, OPC, and SI values so that once the link is established,

other devices that do not have the routing context cannot interfere with communication

to the ASPs.

ASNotify=yes/no. Do you want to notify the Application Server of changes in status in

the ASPs? This should be set to match the needs of the equipment you are

communicating with. Some AS want it on, some want it off.

•Network appearance identifies the SS7 network context of the message, for the purposes

of logically separating signaling traffic between the Signaling Gateway Process and ASP

over a common SCTP association. Use this command to enter a new network appearance

in the Network Appearance table.

•A unique network appearance value can be associated with ANSI, ITUI, 14-bit ITU-N or

24-bit ITU-N networks.

•When the ITUDUPPC ( ITU National Duplicate Point Code) feature is turned on, network

appearance can be associated with a specific 14-bit ITU-N group code.

•The network appearance table can contain a maximum of 45 entries

Bearer Independent Call Control protocol is a call control protocol used

between serving nodes. This protocol is based on the ISUP protocol, and was adapted to

support the ISDN services independent of the bearer technology and signaling message

transport technology used.


•The feature is enabled using the feature’s part number and feature access key.

•The feature access key for the Large BICC MSU Support for IP Signaling feature is based

on the feature’s part number and the serial number of the EAGLE 5 STP, making the

Course Notes


• The rept-stat-card command also shows information not depicted on this slide concerning GPL

versions, IMT bus status and card temperature information

• The rept-stat-card : mode = full command will provide TVG status details

Note: You must enter the card slot location to use the “mode=full” parameter


rept-stat-assoc

Reports status for all associations


•rept-stat-slk

Reports status, alarms and unavailable reason for signaling links

•rtrv-slk

Shows the slktps assigned to the links


The rept-stat-iptps command is used to display the current and peak IPTPS usage for

each IPSG linkset in the system or for each link in the IPSG linkset

• Reports the current number of transactions and peak transactions per second

• Reports on IPSG M2PA and M3UA

• Reports on IPGW

• Command uses (Number of IS-NR links * SLKTPS) in place of the IPTPS setting for all

calculations and alarms.

• If the linkset is specified with the peakreset=yes parameter, then the command

recalculates peaks for the specified linkset and resets all the stored peak values to the

current actual usage for each link contained in the linkset before reporting usage.


Pass Command Syntax:

•Inside the quoted portion, you don’t use colons as separators

•Inside the quoted portion, you don’t use parameter=value pairs

See the “Pass-through Commands” chapter of the Commands manual of the user

documentation for a complete list of pass commands.


Pass Commands Examples

•aslog <applicationServer>

•assocrtt <associationName>

•connmgr –n

•linkinfo <link> –l

•msucount –l a

•msucount –a <associationName>

•netstat –p sctp

•sctp –a <associationName>

NOTE: The MSUTRACE pass command should be used only by request of Tekelec

support centers.


•Ping: Isolate breaks in the communications path using regular isolation methods. Ping

yourself, ping the far end, ping routers along the way until you have located the area of

communications breakdown. Copy and paste a host name from the ent-assoc command to

verify that you have typed it right.

•NSLookUp: Not very useful unless you are using DNS servers.

•arp –a: This shows MAC and IP addresses. If IT doesn’t tell you what the default routers

are, they will show up in this report.

•arp -f: This flushes all of the MAC addresses out of the buffer. If you change protocols or

MAC type, you will have to flush buffers on both ends of the association before it will come

up.

•netstat –p sctp: Shows aggregated report of all the sctp buffers on the card. Use this to

identify overall problems then isolate with sctp command (later).

•traceroute: The roundtrip time should be under 120 ms for basic functionality, and lower

than 40 to 70 msec for full bandwidth. If the roundtrip time begins to drop (see assocrtt),

use this to see what routers your messages are going through and how much delay each

router is introducing. Warning- This command uses UDP protocol. Your SCTP packets

might not follow exactly the same path.


connmgr –d: Displays a list of all MTP3 links (a, a1, a2, etc.) and whether they are connected to the

sctp layer correctly

connmgr –i: Shows an instance of an SCTP connection. If an SCTP connection is bouncing, this

number will continually change to show that. Also, this list shows how many SCTP connection

requests were refused by the other end.

connmgr –l: This provides a log of all changes in status. If connmgr –I shows a refused connection,

this log will show the date and time of the refusal and what events went on around that time.

connmgr –n: This provides a log of association status. If associations bounce, this log will show

when the link bounced and what commands were involved.

connmgr –r: (Reset) Clears all connmgr measurements and logs.

sctp –a [aname]: This report displays provisioned information plus it displays SCTP

performance information similar to netstat –p sctp. The difference is that the information will be

for a specific association instead of generic to all associations on the card. Note- This will only

reports on SCTP associations that are up. If the association is not coming, refer to connmgr –n

to see why not.

sctp –l: This provides a log of maintenance messages issued on both the data stream and the

maintenance stream. The date and time and the “reason” the message was issued are

especially valuable.

sctp –r: This resets all sctp logs and measurements.

assocrtt [aname]: For associations to work correctly, acknowledgements must be returned within

120 msec of when they went out. For full performance, this round trip time has got to be under

40 to 70 msec. Do not use Ping to time this. This command is used for diagnostic purposes as

well as setting congestion windows and retransmit times.

assocrtt [aname] –r: Resets assocrtt statistics. Use this to measure performance over specific


periods. Issue this at the beginning of the period. Then issue assocrtt [aname] at the end of the

period to discover how much they varied over that period.

linkinfo [slk] –a: Provides a time stamped log of link changes in link states. It can report changes

from MTP3 to MTP3 (State) or changes between MTP3 to M2PA (m2pa). Which of these are

reported are determined by the –i, -x, and –v switches.

linkinfo [slk] –l: Provides a time stamped log of primitives. Primitives are messages are issued

between layers. The –i,-x, and –v switches can be selected to determine which primitives will

be displayed. The report can include messages between MTP3 and SCTP (l3l2), SCTP to

MTP3 (l2l3), data, and service messages. Which reports are included depend on –i, -x, -v

switches.

linkinfo [slk] –r –a: Resets the link change log.

linkinfo [slk] –r –l: Resets the SCTP primitive log.

msucount –a [aname]: Counts MSUs received and transmitted on a given association. It also counts

bytes.

msucount –l [slk]: Counts MSUs received and transmitted on a given signaling link. It also counts

bytes.

msucount –r : Resets the counts of MSUs received and transmitted.

msutrace: Do not use this command unless directed to by Customer Service. They will walk you

through it at that time.


Useful tools for verifying SIGTRAN issues are:

• EAGLE UAMs and UIMs

• Enter the command chg-trm:all=yes:trm=x to see all messages generated by the

EAGLE 5 STP

• wireshark (ethereal)

• Eagle Documentation

• RFCs

Tekelec STP software prior to Release 38 does not support IP based measurements.

The following EAGLE STP Manuals will be used as reference for this section of the course.

• Commands

• Maintenance


•Entity types: Link, Lnkset, SCTPASOC, SCTPCARD, UA

•Accumulation interval: 30 minutes

•Optional MP Accumulation interval: 15 minutes

•STP retention period: 24 hours

•Reporting modes: Scheduled, On-Demand

•Accessible collection periods: Last, Specific, Active



•Accumulation interval: 24 hour






To find the signaling link occupancy percentage, divide the amount of MSUs transmitted and

received per 30 minute period by maximum 3,600,000 MSUs per 30 minutes multiplied by

100.

Maximum MSUs per 30 Minutes: 2000TPS X 60 sec. X 30 min. = 3,600,000 MSUs

To find the 24-hour signaling link occupancy percentage, divide the amount of MSUs

transmitted per 24 hour period (determined by the Daily Maintenance measurement report) by

maximum 172,800,000 MSUs per 24 hour period multiplied by 100.

Maximum MSUs per 24 hour period: 2000 X 60 sec. X60 min. X 24 hrs. = 172,800,000 MSUs

Signaling Link Occupancy Calculations are typically calculated only on the transmit buffer of a

signaling link. They may also be calculated on the higher of the two buffers transmit, or

receive.

IP signaling link occupancy is calculated on MSUs (TPS) per second. You can monitor this

using the rept-stat-iptps command for IPLIM link sets and signaling links for IPGW.


To find the signaling link occupancy percentage, divide the amount of MSUs transmitted and

received per 30 minute period by maximum 9,000,000 MSUs per 30 minutes multiplied by

100.

Maximum MSUs per 30 Minutes: 5000TPS X 60 sec. X 30 min. = 9,000,000 MSUs

To find the 24-hour signaling link occupancy percentage, divide the amount of MSUs

transmitted per 24 hour period (determined by the Daily Maintenance measurement report) by

maximum 432,000,000 MSUs per 24 hour period multiplied by 100.

Maximum MSUs per 24 hour period: 5000 X 60 sec. X60 min. X 24 hrs. = 432,000,000 MSUs

Signaling Link Occupancy Calculations are typically calculated only on the transmit buffer of a

signaling link. They may also be calculated on the higher of the two buffers transmit, or

receive.

IP signaling link occupancy is calculated on MSUs (TPS) per second. You can monitor this

using the rept-stat-iptps command for IPLIM link sets and signaling links for IPGW.
