Patton's Model 2711 pocket-sized converter-CSU/DSU makes it simple and affordable to connect V.35 to T1 or Fractional T1 (Nx64)

--Image: RACKABLE! Rack Mount Available --The Patton Model 2711 T1-to-V.35 interface converter-CSU/DSU connects to a 4-wire T1 circuit and plugs directly into the V.35 interface of a router, switch or multiplexer. Connecting to an unstructured T1 circuit at 1.544 Mbps, the Patton 2711 also supports n x 56/64 framed connections at data rates from 128 kbps to 1.536 Mbps. In addition, the Patton 2711 may be used in pairs in point-to-point applications, where it is able to connect two V.35 devices at data rates to 1.544 Mbps over distances to 6,000 ft (1.14 miles/1.82 km). Adapter cables are available to connect the Patton 2711 to WAN equipment that does not use a standard V.35 interface (such as the Cisco 2501 router, which uses a high-density 60 pin connector).

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 build out (LBO) levels. These parameters are user configurable via internal DIP switch settings. The Patton 2711 is also switch-configurable for clear channel (1.544 Mbps) or fractional (nx 56/64 kbps) operation. Fractional settings include 2, 4, 6, 8, 12, 16 and 24 channels (for example, setting the 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 has seven diagnostic LEDs. Diagnostics include response to Central Office initiated D4 loopup and loopdown codes, ESF line loop and payload loop FDL messages, and universal loopback de-activate message. Power is supplied to the Patton 2711 by an external AC transformer.
