Applications

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.

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.

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. 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 (-20^oC to +70^oC) and Extreme Temp Option (-40^oC to +80^oC) are available.
