ADTRAN T3 Fiber Access
MX2800 M13 Multiplexer

Overview:

M13 remains an important part of network operations. Carriers need M13 elements that are reliable, cost effective, and conserve space. ADTRAN^TM has applied its industryleading carrier-class expertise to the MX2800TM M13 multiplexer, creating a product that meets the most stringent carrierclass requirements. The MX2800 offers bandwidth consolidation at a low price and in the smallest footprint available in the industry. The equipment meets stringent NEBS Level 3 requirements and is backed by a 10-year warranty. Measuring only one rack unit high in 19-inch or 23-inch rackmount configurations, this compact device gives NSPs and enterprise users a powerful tool for consolidating 28 T1 signals or 21 E1 signals into a T3 circuit. The MX2800 is also available in an STS-1 version.

The MX2800 houses two hot-swappable controller cards that are capable of combining independent T1s, E1s, or T1s and E1s, on the same DS3. The two controller cards also provide built-in 1:1 redundancy for the DS1 and DS3 signals as well as redundant DS3 connections. Advanced diagnostics include CSU loopbacks, NIU loopbacks, C-bit loopbacks and built-in BERT (Bit Error Rate Testing) capabilities. A fully connectorized backplane means no wire wrapping and quick, easy installation. Accessories available for the MX2800 include a DS1 patch panel that breaks out the 28 DS1s into 28 individual RJ-48 interfaces and a battery backup system that provides eight hours of battery backup.

As with all ADTRAN products, the MX2800 offers comprehensive management options, including full management and GUI support from ADTRAN’s Total Access® EMS. It features a VT100 terminal interface for local configuration. To support SNMP and Telnet management, the MX2800 has an integrated 10Base-T Ethernet port. Also available is an optional integrated V.34 modem operable in VT100 mode or SLIP/PPP mode for SNMP and Telnet access. The modem is capable of performing a dial-out “cry for help” for units that are located in unmanned facilities.

Carriers who want to maximize their copper investment and consolidate services in the most efficient manner will find that the MX2800 will pay off quickly. For example, a bandwidth reseller who is co-located at an unmanned site and backhauling local and long distance voice service can use the MX2800 to gain T1 access off Hi-Cap SONET rings. The MX2800 is also ideal for Competitive Local Exchange Carriers (CLECs) who are also looking for an efficient means for backhauling local and long distance voice to or from the IXC or LEC. As Internet use continues its rapid expansion, Internet Service Providers are also well served with the MX2800’s bandwidth consolidation.
