Description
The model TC8518 High
Capacity T1/E1 & Ethernet Multiplexer gives users the cost saving benefits of
minimal hardware and fiber conserving efficiency along with a wide array of
important features. Key features include Web Management, Statistics Monitoring,
Network Time Server (NTS), and the Extreme Temp version.
It multiplexes
4, 8, 16, 20**, or 24** T1 channels or 4, 8, 16 or 20* E1 channels and a 3 port
Ethernet switch (combined bandwidth of 100Mbps) over multimode (1300nm) or
single mode (1300/1550nm) fibers. The Ethernet ports support non-blocking full
100Mbps total bandwidth.
Optional Voice (up to 8 channels FXS/FXO
or 4 channels 2 Wire/4 Wire Analog) or Data (up to 8 channels
RS-232/RS-422/RS-485)
Setup, diagnostics, and control are accessed via Web, Serial Console, Telnet or
SNMP management. Diagnostics include LED indicators, dry contact alarms, and
local and remote loop back to assist with troubleshooting and maintenance.
Statistics Monitoring keeps a history of all activity (optical, T1/E1,
Ethernet).
VLAN, Statistics Monitoring, Remote Firmware Upgrades, Network Time Server,
Temperature Monitoring, and Ethernet Rate Limiting features are standard. The
Ethernet switch is IEEE 802.3/802.3u/802.3x compliant and supports Huge Frames
(1916 bytes). Each T1 or E1 channel is independent and transparent to the
framing format and supports all applicable standards and line codes.
The TC8518
supports distances up to 100 km and offers a two-way "one fiber" WDM
communication option to maximize fiber cable usage by transmitting and receiving
data through a single fiber strand. The TC8518 also supports
the OC3 interface. Redundant power and optics are standard,
including automatic switchover for maximum reliability.
The TC8518 is available in 1U high “Rack Mount.” Fiber optic connectors are SC.
Standard power is 100-240VAC; 24, -48, 125VDC power options are optional. All
power supplies are hot swappable. For industrial environments, the High Temp
Option (-20oC to +70oC) and Extreme Temp Option (-40oC
to +80oC) are available.

Typical Application
(Application Questions)
Typical applications include connecting
T1/E1 signals from Cell Towers to Central Offices, linking multiple T1/E1
links between remote sites and adding Ethernet service to existing T1/E1
fiber optic links.
Service Providers use the TC8518 as an efficient, cost
effective method to provide their customers with Ethernet (full 100 Mbps
bandwidth
and can be rate limited in 32kbps increments)
connections for data and T1 for voice.
The "two-way one fiber" option can
double usage of existing fiber optic cable plants.
