TC8518
T1/E1, Data/Voice & Ethernet Fiber Optic Multiplexer (4-24 Ch.)

The TC8518 T1/E1, Data/Voice & Ethernet Fiber Optic Multiplexer multiplexes 4/8/12/16 channels of T1/E1 and 3 Ethernet ports on a single mode (1300/1550nm) or multimode (1300nm) fiber. It can also multiplex additional T1/E1, voice, analog and data channels via an expansion card with any one of the following options:

Expansion Card (for T1 unit):
  • Telephone: 4/8 - FXS or FXO
  • Analog: 4 - 2/4 Wire
  • Serial: 4/8 - RS232/422/485
  • T1: 8 channels
Expansion Card (for E1 unit):
  • Telephone: 4/8 - FXS or FXO
  • Analog: 4 - 2/4 Wire
  • Serial: 4 - RS232/422/485
  • E1: 4 channels

Each T1 or E1 channel is independent and transparent to the framing format and supports all applicable standards and line codes. The 3-port Ethernet switch supports non-blocking full 100Mbps bandwidth, VLAN, and Rate Limiting. It is IEEE 802.3/802.3u/802.3x compliant and supports Huge Frames (1916 bytes).

The TC8518 supports distances up to 100 km and offers a one fiber, bi-directional WDM option to maximize bandwidth. Setup, diagnostics, and management are accessed via Web, SNMP, Serial Console, and Telnet. Diagnostics include LED indicators, dry contact alarms, and local and remote loopback. Statistics Monitoring keeps a history of activity (optical, T1/E1, and Ethernet).

A 1U high “rack mount” chassis and power/fiber optic redundancy are standard. Fiber redundancy includes automatic switchover for maximum reliability. Standard power is 90-260VAC; power supplies are hot swappable. Optional power supplies include 24VDC, -48VDC, and 125VDC. Fiber optic connectors are SC. A high temperature version (-20°C to +70°C) and extreme temperature version (-40°C to +80°C) are optional.

Applications

Typical applications include connecting T1/E1 signals from Cell Towers to Central Offices, multiplexing T1/E1 links between PBX’s, and adding Ethernet, Analog, Data or Telephone service to existing T1 or E1 fiber optic links.

Service Providers use the TC8518 as an efficient, cost effective method to provide their customers with Ethernet (100Mbps Total Bandwidth) for data and T1/E1 for voice. Analog channels can be used for radio applications.

The one fiber, bi-directional optic option doubles existing fiber optic cable capacity.
