ATM Line Cards

The 8955, 8965, 8968, and 8985 Asynchronous Transfer Mode (ATM) Line Cards are circuit boards mounted in an 8620 or 8820 Broadband Access Concentrator (BAC) and used to transport ATM cells at high speeds over a single twisted-pair connection or, optionally, two twisted-pair connections (8985 only).

￿Model 8955 supports ReachDSL. It automatically adjusts to the highest rate the loop can support, from 32 to 2176 kbps. It has 24 ports.

￿Models 8965 and 8968 support Asymmetric Digital Subscriber Line (ADSL). They can be set to adapt to the line conditions at startup, or set to the following fixed rates depending on line code:

—G.lite: 64 to 3008 kbps downstream and 32 to 512 kbps upstream.

—G.dmt, ANSI T1.413, ADSL2, and ADSL2+: 32 to 8000 kbps downstream and 32 to 832 kbps upstream.

—ADSL2: 32 to 16000 kbps downstream and 32 to 1056 kbps upstream.

—ADSL2+: 32 to 29000 kbps downstream and 32 to 2200 kbps upstream. The Model 8965 has 24 ports and the Model 8968 has 48 ports.

￿Model 8985 supports Single-pair High-speed Digital Subscriber Line (SHDSL). It can be set to adapt to the line conditions at startup, or set to a fixed line rate from 192 to 2304 kbps (or 384 to 4608 kbps with two wire pairs). It has 24 ports.

The 8955, 8965, 8968, and 8985 line cards are configured and managed using the Shelf Concentration and Processing (SCP) card.

Part of Paradyne’s Hotwire Connected™ program, the cards interoperate with third-party DSL endpoints providing end users with the ability to select the best equipment to fit their application. The line cards also integrate support for multiple DSL services on a single card.
