CHAPTER 1
Introducing the VOP1372G
This chapter introduces the VoIP line card's general features and hardware.
1.1 VOP1372G Overview
The VOP1372G VoIP Line Card is perfect for telecommunications providers, ISPs or large building
applications seeking to provide phone service via Voice over IP (VoIP) to subscribers while
minimizing costs. One VOP provides VoIP telephony service for up to 72 subscribers over existing
POTS telephone wiring.
The line to and from the user carries either voice alone, or both voice and data (ADSL/VDSL)
signals. For each line, a splitter card separates the high frequency ADSL/VDSL signal from the voice
band signal and feeds the voice band signal to the VOP1372G, while the ADSL/VDSL signal is
diverted to the ADSL/VDSL line card (ALC1372G or VLC1348G, for example).
The VOP1372G supports H.248 (also known as MEGACO - MEdia GAteway COntrol - or the Gateway
Control Protocol).
Each VOP with H.248 firmware can operate as an individual media gateway or as part of acentralized H.248 interface capable of spanning multiple VOPs or chassis and managing up to1200 subscribers. You can use a backup VOP card for higher reliability of H.248 protocolprocessing.
Use the Telco-50 connector pin assignments in Section 2.3 on page 19along with the directions and
safety warnings in the IESs User's Guide to install the line card and make the necessary
connections.
See the MSCs Users Guide for detailed information on configuring the line card.

Configurable POTS Ring Patterns
You can configure POTS (Plain Old Telephony Service) distinctive ring patterns. These ring patterns
define the ring the VOP sends to the connected POTS phones for incoming calls.
European and USA Supplementary Phone Services
The VOP supports both European and American style supplementary phone services (call hold, call
waiting, call transfer and three-way conference calls).
IEEE 802.1Q Tagged VLAN
Your VOP uses the IEEE 802.1Q Tagged VLAN (Virtual Local Area Network), which allows it to
deliver tagged/untagged frames. The IES supports up to 4094 individual VLANs.
Quality of Service (QoS)
The VOP supports IEEE 802.1p QoS (Quality of Service) network traffic prioritization for RTP traffic,
as well as DSCP (Differentiated Services Code Point) and ToS (Type of Service) tagging.
3-way Conference Call
The VOP can combine two calls of different codecs into the same conference call.
Analog Modem Pass-through
The VOP supports analog modem service over the voice channel.
Fax Pass-through and T.38 Relay
The VOP supports fax service over the voice channel using G.711 or using T.38 relay.
Country Code
Many settings governing call functions differ from one region to another. The VOP allows you to set
these by entering a preconfigured country code. The following variables are affected when you set
the country code.
Ringback tone The remote partys phone is ringing.
Waiting tone The other partys line is engaged.
Howler tone The handset has been left off-hook too long.
Message WaitingIndication (MWI) tone A voicemail message is waiting.
Holding tone The caller has been placed on hold.
Distinctive ring The VOP has a list of ring patterns based on country codes that the H.248 MediaGateway Controller (MGC) can have the VOP send to the connected telephones.

Comfort Noise Generation
Your device generates background noise to fill moments of silence when the other device in a call
stops transmitting because the other party is not speaking (as total silence could easily be mistaken
for a lost connection).
Dynamic Jitter Buffer
The built-in adaptive buffer helps to smooth out the variations in delay (jitter) for voice traffic. This
helps ensure good voice quality for your conversations.
Tx/Rx Gain
The VOP allows you to increase or decrease the volume of the audio signal sent to and received
from the subscriber.
VPI (Voice Packetization Interval)
The VOP allows you to configure the amount of audio information (measured in milliseconds)contained in each packet of data transmitted.
1.2.1 H.248 Features
Centralized and De-centralized Structure
For ease of management, you can use multiple VOPs as part of a centralized H.248 interface that
can span across multiple VOPs and even multiple chassis in order to manage up to 1200
subscribers. A centralized H.248 interface makes it easy to scale up as the number of subscribers
increases. You can add cards and subscribers with a minimum of configuration and without
interrupting existing DSL or VoIP services. The following graphic shows an H.248 interface thatincludes VOPs in three different chassis.

You can also deploy individual VOPs with H.248 firmware as stand-alone H.248 interfaces. The
following graphic shows VOPs in three different chassis where each VOP is configured as a separate
H.248 interface.
Figure 2 De-centralized VOPs Deployment
MGC Redundancy for Higher Reliability
You can configure the H.248 interface to use a second (backup) MGC in case the first MGC is not
available.
Figure 3 MGC Redundancy
H.248 Signaling Card Redundancy for Higher Reliability
An H.248 interface consists of a Signaling Card (SC) and at least one Media Card (MC). A
VOP1372G-61 can act as either an SC, an MC, or both. The SC processes H.248 protocol messages

from the MGC. The MC handles the RTP payload and converts it into analog for the subscribers
phone. The MCs are also known as an SCs slaves. You can install a second VOP card to back up the
H.248 interfaces SC. If the active SC fails, the backup SC takes over the processing of the H.248
protocol messages so the H.248 interface can continue to provide service.
Figure 4 H.248 Interface with Backup Signaling Card
Remote Ringback Tone Generation
The VOP can send a remote ringback tone to the caller so they hear that the phone connected to
the VOP is ringing.
Call Overload Protection
You can configure how many calls the H.248 interface is to handle. This protects against
overloading the VOP cards or the MGC.

CHAPTER 3
Troubleshooting
This chapter offers some suggestions to solve problems you might encounter. The potential
problems are divided into the following categories.
Power and LEDs
Management and Configuration
3.1 Power and LEDs
The SYS or PWR LED does not turn on.
The ALM LED is on.
The ALM(alarm) LED lights when the line card is overheated or the voltage readings are outside
the tolerance levels.
Table 10 SYS LED Troubleshooting
STEPS CORRECTIVE ACTION
1 Make sure the power wires on the chassis are properly connected to the power supplyand the power supply is operating normally. Make sure you are using the correct powersource (refer to the IES Users Guide).
2 Make sure the power wires are connected properly.
3 Make sure the line card is properly installed.
4 The LED itself or the unit may be faulty; contact your vendor.
Table 11 ALM LED Troubleshooting
STEPS CORRECTIVE ACTION
1 Use the sysmoni t or show command to verify the cause of the alarm. See step 2 if the unitis overheated, and step 3 if the voltages are out of the allowed ranges.
2 Ensure that the IES is installed in a well-ventilated area and that normal operation of the fans isnot inhibited. Keep the bottom, top and all sides clear of obstructions and away from the exhaustof other equipment.
3 If the voltage levels are outside the allowed range, take a screen shot of the sys moni t orshowcommand display and contact your vendor.

3.2 Phone Calls
I cannot make or receive H.248 phone calls on a phone connected to the VOP.
3.3 Management and Configuration
The line card is not manageable.
The line card always uses the default configuration. Any changes you made to the line card are
stored on the MSC. By default, the MSC is allowed to manage every line card. Use the l cman showcommand on the MSC to see a line cards connection status. If you still cannot manage the line card
from the MSC, the line cards configuration file may be damaged or the firmware may be old, you
may need to restore the default configuration file or upload new firmware using the line cards
console port.
Table 12 Phonecall Troubleshooting
STEPS CORRECTIVE ACTION
1 Ensure that the hardware is correctly installed and functioning as described in the IES UsersGuide.
Ensure that the VOP is running H.248 firmware.
Ping the H.248 media gateway controller from the line card to ensure that it is reachable.
2 Check to see whether the port is successfully registered with the H.248 MGC. Use the showl i nestat command to see if a port is in service (registered) or out of service (notregistered).
3 The line card or the port may be disabled.
Use the l cman showcommand to check the slot status, and the l cman enabl e commandto activate a slot.
Use the por t show command to check the port status, and the por t enabl ecommand to activate a port.
4 The port may be set to use the wrong virtual media gateway or DSP profile. Use the por t h248set command to set the port to use the correctprofiles.
5 The H.248 profile, virtual media gateway or DSP profile may be mis-configured.
Use the pr of i l e voi p h248 show [ ] command to check the H.248 profile.
Use the voi p h248 mg show * command to check all virtual media gateways.
Use the prof i l e voi p dsp show [ ] command to check the DSP profile.
6 Check any hardware between the phone and the VOP. Try using another telephone, another porton the VOP, or both. Run the MLT (Metallic Line Test) on the relevant port (use the di agnost i cml t t est commands).

4 After a successful configuration file upload, type atgoto restart the line card.
3.3.2 Uploading the Firmware via Boot Commands
Usually you should use FTP with the MSC to upload the line cards firmware. If you cannot manage
the line card from the MSC, use the following procedure to upload firmware to the line card.
1 Obtain the firmware file, unzip it and save it in a folder on your computer.
2 Connect your computer to the console port and use terminal emulation software configured to thefollowing parameters:
3 Pull out the line card and push it back in to restart it and begin a session.
4 When you see the Pr ess any key t o ent er Debug Mode wi t hi n 3 seconds message,press a key to enter debug mode.
5 Type atba5after the Ent er Debug Modemessage (this changes the console port speed to
115200 bps).
