Carrier Access MASTERseries IAD Platform

Carrier Access MASTERseries is used for Radio Access Network - RAN hubbing and concentration, Cell site integrated access, Cell site LAN extension/IP aggregation, site to site ADPCM transcoding (voice compression), and
Fault tolerant SS7 transport.


Reduces backhaul circuit costs with granular channel grooming and optional transcoding
Reduces operating expenses with remote management, integrated BERT, and test capability
Eliminates cell site POTS lines with optional IP routing and portable FXS ports
Reduces service outages with a rugged platform, lightning protection, and automatic protection switching (APS)
Reduces capital costs of buying single purpose devices with a multi-services modular platform
Reduces space and power requirements with a compact design

Application Modules

?a T1/E1 compact digital crossconnect switch with integrated DSU/CSU functionality targeted at hub locations, base station sites, and customer premises. The PATHmaster comes in two, three, and four T1/E1 port configurations and each includes two V.35 or RS-530 data ports. Two- and three-port versions are remotely software-upgradeable to activate all four ports.

?expands the capabilities of the PATH master by adding 2:1 ADPCM voice compression for supporting dual mode AMPS and digital cell sites. The TRANSmaster is also used for MTSO-to-MTSO and PSTN connection applications.

?a four T1/E1 inverse multiplexer with integrated crossconnect capability that is used to front-end microwave radios for high-speed data applications and/or to provide multi-megabyte data connectivity at branch offices.

?a high-density four port serial module that is used for data channel bank applications such as SS7 channel consolidation between mobile switching center locations.

?a multi-link CSU that provides connections for up to two full or fractional T1/E1 circuits. The LINKmaster provides four T1/E1 ports with integral CSU/DSX-1 circuitry on all links. The LINKmaster functions as a low cost dual CSU or repeater application module and is remotely software-upgradeable to full PATHmaster functionality.

?a five-port 10/100 MB Ethernet hub. The HUBmaster is environmentally hardened and expands the number of Ethernet ports available while conserving space.

?a quad-port Ethernet 10/100 hub with a quad port asynchronous terminal server that expands the capabilities of the PACKETcore IP bridge/router module to provide additional Ethernet hub ports and to network-enable the remote management and control of serial devices that might otherwise be unreachable.

Plug-on Modules & IP Routing

?a compact, high performance IP/IPX router that is an optional upgrade to the MASTERseries application modules, excluding HUBmaster and DATAmaster. It features integrated firewall, a single 10/100 Ethernet port, two serial ports, and robust IP/IPX routing.

?a portable full function FXS port that is used to eliminate costly POTS lines at BTS sites by integrating standard PSTN connectivity into the T1/E1 backhaul circuit. The TELEport?s unique portability allows for the plug-on to be shared between BTS locations and used only when needed ? further reducing the costs associated with direct PSTN connectivity at cell sites.

?a full function, portable IP access router designed to provide cost-effective LAN connectivity in cell sites and remote locations.
