T1 CSU/DSU is also a 1.544 Mbps Campus Modem7.10.1998 GAITHERSBURG, Maryland, USA, July 10, 1998 - Patton Electronics Company has just unveiled a T1-to-V.35 interface converter that also functions as a T1CSU/DSU and campus short range modem. The Patton 2711 connects to a 4-wireT1 circuit and plugs directly into the V.35 interface of a router, switch ormultiplexer. Connecting to an unstructured T1 circuit at 1.544 Mbps, thePatton 2711 also supports nx56/64 framed connections at data rates from 128kbps to 1.536 Mbps. In addition, the Patton 2711 may be used in pairs inpoint-to-point applications, where it is able to connect two V.35 devices atdata rates to 1.544 Mbps over distances to 1.14 miles/1.82 km. The Patton 2711 supports D4/AMI or B8ZS/ESF line coding and framing,internal or network clocking, and selectable 0, 7.5 or 22.5 db line buildout (LBO) levels. These parameters are user configurable via internal DIPswitch settings. The Patton 2711 is also switch-configurable for clearchannel (1.544 Mbps) or fractional (nx56/64 kbps) operation. Fractionalsettings include 2, 4, 6, 8, 12, 16 and 24 channels (for example, settingthe Patton 2711 at "224/256 kbps" would activate four 56/64 kbps channels). Measuring only 4.6" long, 2.1" wide and 0.81" high (11.6 x 5.3 x 2.1 cm),the Patton 2711 incorporates one RJ-48C jack for modular connection to thenetwork and one M/34 connector that plugs directly into a standard V.35interface on a router, switch or multiplexer. Non-standard V.35 adaptercables are available from Patton; for example, M/34 to HD-60 for use withCisco routers. The Patton 2711 has seven diagnostic LEDs showing transmit data (TXD),receive data (RXD), loss of sync (LOS), alarm (ALM), error (ERR), test (TST)and power (PWR). Diagnostics include response to Central Office initiatedD4 loopup and loopdown codes, ESF line loop and payload loop FDL messages,and universal loopback de-activate message. Power is supplied to the Patton2711 by an external AC transformer. Applications Pricing and Availability About Patton Patton Electronics is an ISO 9001 certified and BABT approved manufacturer.
