Installation Procedure Chapter 2: Installation and Setup

Installation Procedure

This chapter describes installation and setup procedures for the PINE-E1 unit.

Internal settings, adjustment, maintenance and repairs may be performed only by a skilled technician who is aware of the hazards involved.

Always observe standard safety precautions during installation, operation and maintenance of this product.

The PINE-E1 interface converter is designed for standalone installation and is delivered as a fully assembled unit.

Package Content

The PINE-E1 package includes the following items:

• One PINE-E1 unit

• Technical documentation CD

• AC and DC Power cords

• RJ45 to Rosset Box for E1 connectivity

Site Requirement and Prerequisites

AC-powered PINE-E1 units should be installed within 1.5m (5 ft) of an easily-accessible grounded AC outlet capable of furnishing the required supply voltage, in the range of 100 to 240 VAC.

DC-powered PINE-E1 units require a -36 to -72 V DC power source, which must be adequately isolated from the mains supply.

Allow at least 90 cm (36 in) of frontal clearance for operator access and interface cable connections.

The ambient operating temperature of PINE-E1 is 0 to 45°C, at a relative humidity of up to 95%, non-condensing.

PINE-E1 Installation Procedure

Connecting to Power

PINE-E1 is equipped with either AC or DC power supply. AC or DC power is supplied to PINE-E1 via a standard power input connector on the front panel.

Connecting to AC Power AC power should be supplied through the standard power cable terminated by a standard plug. The cable is provided with the unit.

To connect AC power:

1. Connect the power cable to the power connector on the PINE-E1 front panel.

2. Connect the power cable to the AC mains outlet.

The unit turns on automatically upon connection to the AC power mains.

Connecting to DC Power DC power is supplied to PINE-E1 via a compatible DC cable for attaching -48V DC power supply lines. While connecting to the DC power mains, the polarity needs to be taken care as per the indications provided on the DC cable. This includes -48, Earthing and 0V connection terminals. These connections terminals are to be separately connected.

The DC power cord is provided along with the unit.

Connecting the E1 port

The PINE-E1 provides E1 (Balanced 120 Ohms, RJ-45 connector) interface for synchronizing input/output data, clock reference and control signals between the E1 interface of the Converter and the Service provider’s E1(Refer Appendix C for pin-out details).

To connect E1 interface

Connect the Service provider’s E1 cable to the designated E1 interface located on the front panel.

Connecting the Ethernet Port

The Ethernet port of PINE-E1 uses CAT-5 cable for Unshielded Twisted Pair RJ-45 connector and it can transmit data up to 100 meters. (Refer Appendix-C for pin-out details)

To connect Ethernet interface

Connect the Ethernet interface of CPE equipment (PC, Switch, Router and etc) to the Ethernet interface of Converter using appropriate Ethernet cable.

Configuring DIP-Switch PINE-E1

Configuring DIP-Switch

PINE-E1 can be configured using Dip-Switches SW1 to SW6 on rear panel of the PINE-E1 module.

Following are five 8-bit dip switches in rear panel used for configuring PINE-E1

• SW1 - To configure the Systems parameters

• SW2 , SW3, SW4 & SW5 – To configure the E1 Unframed / Framed mode & Timeslots selection

SW6 is a 8-bit dip switch in rear panel used to configuring Buffer size selection

Before switching ON the power supply, configure all dip switches and connect the E1 cable

Configuring switch SW1:

PINE-E1 Configuring DIP-Switch

First Bit

To Select Ethernet Auto Negotiation Function

ON - To disable auto-Negotiation function.

OFF - To enable auto-Negotiation function (default).

When the auto-Negotiation function of Ethernet interface is enabled, the auto MDI/MDIX capability is enabled simultaneously. Ethernet interface has 10/100M auto-sensing function.

If the Ethernet interface mode of switch, hub and PC is fixed (10/100 Mbps Full/Half), then the PINE-E1’s Ethernet working mode is half-duplex only (If Auto Negotiation is enabled in PINE-E1).

When the Auto-Negotiation capability of Ethernet interface is disabled, the auto MDI/MDIX capability is disabled simultaneously.

The Ethernet working mode of PINE-E1 is determined by 2nd and 3rd dip switch of SW-1, if Bit 1 is ON (Auto Negotiation disabled).

Second Bit

Ethernet interface Speed selection - 10/100Mbps operation

ON - 10Mbps

OFF - 100Mbps (default)

This switch is invalid when 1st dip switch is in OFF mode.

Third Bit

Ethernet interface Duplex mode selection switch – Half / Full duplex

ON - Half-Duplex

OFF - Full-Duplex (default)

This switch is invalid when 1st dip switch of SW-1 is in OFF mode.

Fourth Bit

Fault-Pass-Through selection switch

ON - To enable Fault-Pass-Through function between E1 and Ethernet interface

OFF - To Disable Fault-Pass-Through function between E1 and Ethernet interface (default)

If Fault-pass-through is enabled, Local LOS, LOF, AIS and CRC alarms of E1 link can disable the Ethernet interface to report E1 link fault to CPE equipments (Switch, Router and PC etc).

If there is no alarm on E1 link, the Ethernet interface resumes normal working status automatically.

There is no association between the working status of Ethernet interface and E1 alarm if E1 fault-pass-through function is disabled.

Fifth Bit

The fifth bit is reserved for future use.

4-3

Configuring DIP-Switch PINE-E1

Sixth Bit

Clock mode switch

ON – External E1clock mode (default)

OFF – Internal Clock mode

If there is timing equipment in E1 link, PINE-E1 on local and remote sites should be set in External E1 clock mode.

The seventh and eighth bits are reserved for future use.

Configuring switches SW2 to SW5

First Bit of SW2

To select Framed/unframed mode of E1 operation

ON - E1 is in framed mode, transmission bit rate is N*64Kbps where N=1~31

OFF - E1 is in unframed mode, transmission bit rate is 2048Kbps (default)

When the working mode of E1 is unframed (default), the 2nd~8th bit of SW2 and SW3~SW5 is invalid. These switches are only available, when 1st bit of SW2 is in ON mode.

2nd~8th bit of SW2 and SW3~SW5

To enable the required Time-slots in E1 framed mode (G.732N).

ON – Time-slot Occupied

OFF – Time-slot not Occupied (default)

The 31 bits switches corresponding with TS1~TS31 of E1 time-slot.

When framed mode is set, it needs to set all 31 bits switches to select time-slot.

ON Framed Time-Slot Configuration

OFF Unframed Not Applicable

When E1 is in framed mode, ensure that all the switches of time-slot occupation is not in OFF mode, at least one switch is in ON mode.

Configuring switch SW6 First and Second Bit: Mode Selection switch

Dip-Switch SW6 is reserved for future use and all bits should be kept in OFF position as a factory default setting

In order to prevent E1 line equipment potential difference oversize. It is suggested that the user should first connect E1 line and then turn ON the power supply. The E1 interface should avoid hotly inserting and pulling out.
