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.

1.3.1.3 Hardware
The TC8518 has these standard features:
• Power, Fiber Redundancy
• Full interoperability and compatibility combined with seamless, transparent
integration with other Layer 2 Ethernet switches
• Local Dry Contact Alarm Relay (DCAR)
• System readout LEDs
1.3.2 Environment
The TC8518 is an industrially hardened platform ruggedized for extreme weather
conditions. The standard temperature option encompasses most environmental
conditions, however, the TC8518 is also offered with an extreme temperature option
for harsh conditions. Each card is monitored for temperature. There are no cooling
fans or filtering devices.
• High Temperature (-20°C to +70°C)
• Extreme Temperature (-40°C to +80°C) Optional
1.3.3 Power
Each TC8518 is furnished with dual power inputs. There are several power supply
input options available, see TC8518 System Configuration, on page 1-6.
• LEDs indicate if power is being supplied to the unit
• Dual power input is available
1.3.4 Management
The TC8518 has the following management features:
• Programmable Unit Alarms
• Remote management (Web, Telnet, SNMP)
• Security
1.3.4.1 Simple Network Management Protocol
Simple Network Management Protocol (SNMP) is used in network management
systems to monitor network-attached devices for conditions that warrant
administrative attention. The TC8518 comes standard with a built-in SNMP Agent.
The MIB file that TC provides is compatible with and may be run on any third party
SNMP Management software. See SNMP Management for a complete description.
