Chapter 1 Introduction

1.1 Introduction

This manual contains a description of the TC8518 as a T1/E1, Data/Voice &

Ethernet Fiber Optic Multiplexer that provides T1/E1, Data/Voice & Ethernet

connectivity over fiber optics. It supports 8/12/16 channels of T1 or E1 and 3-port

Ethernet switch over single mode (1300/1550nm), or multimode fiber (1300nm).

The TC8518 has any one of these options: 8 additional T1, 4 additional E1, 8-

channel voice, 4-channel 2-wire/4-wire analog, 8-channel data (RS-232/RS-422/RS-

485).

This manual intends to:

- document items necessary to define each product and its method of

operation

- provide technical information of the functional capabilities and

performance levels necessary for system level networking designs

1.2 General Information

This manual is for the operation and maintenance of the TC8518. It is intended for

TC Communications factory-trained personnel.

1.3 TC8518 Product Description

This manual contains a description of the TC8518 as a T1/E1, Data/Voice &

Ethernet Fiber Optic Multiplexer that provides T1/E1, Data/Voice & Ethernet

connectivity over fiber optics. It supports 8/12/16 channels of T1 or E1 and 3-port

Ethernet switch over single mode (1300/1550nm), or multimode fiber (1300nm).

TC8518 has any one of these options: 8 additional T1, 6 additional E1, 8-channel

voice, 4-channel 2-wire/4-wire analog, 8-channel data (RS-232/RS-422/RS-485).

It offers advanced features, such as jitter removal and support for AMI, B8ZS

coding for T1 and AMI, HDB3 coding for E1. The TC 8518 offers optimum

flexibility, extremely low current consumption, and high reliability.

Transparent to the framing format, the TC8518's T1/E1 interface shapes the transmit

pulse to support CCITT G.703. Copper line distances for connecting T1/E1 can

range from 0 to 655 feet. The internal elastic buffer removes jitter from the

transmitted data.

Each T1/E1 channel LED indicator eases installation and facilitates troubleshooting.

These LEDs can indicate an Alarm condition, T1/E1 Signal Loss, active Sync status

and more.

The 3-Port Ethernet switch supports half/full-duplex and a combined bandwidth of

100Mbps. The TC8518 supports VLAN* and supports Ethernet Huge Frames (1916

bytes). Each T1 or E1 channel is independent, transparent to the framing format, and

supports all applicable standards and line codes( AMI, B8ZS for T1 and HDB3,

AMI for E1).

Management, setup, diagnostics, and monitoring are accessed via Web, SNMP,

Telnet or Serial Console.

The TC8518 supports fiber optic distances up to 100 km and offers an optional two-

way, "one fiber" communication option to maximize fiber cable usage. Standard

redundant power and redundant optics including automatic switchover ensure

maximum reliability.

Highly cost effective when used to multiplex T1/E1 channels & 10/100 Ethernet

over a single duplex fiber, the TC8518 is often used in interconnecting PBXs in

different buildings, extending satellite down links, transmiting beyond the normal

limitation of twisted pairs (without a repeater), or connecting cell sites to central

offices.

The TC8518 is available in basic stand-alone or 1U high rackmount. SC Optical

Connectors and RJ-48F ports are standard. Standard power is 90/260VAC and

includes redundant power supplies. Optional power sources include 24VDC,

48VDC, and 125VDC.
