Fast Serial Interface Processor (FSIP)

The FSIP (see the following figure) provides four or eight high-speed serial ports (up to 6.132 Mbps). Each FSIP comes with a default dual-port port adapter, PA-7KF-SPA, as follows:

The 4-port FSIP (CX-FSIP4) comes with two dual-port port adapters, which can support X.21, EIA/TIA-449, EIA/TIA-232, V.35, or EIA-530.
The 8-port FSIP (CX-FSIP8) comes with four dual-port port adapters, which can support X.21, EIA/TIA-449, EIA/TIA-232, V.35, or EIA-530.

Note The FSIP4 has one serial port adapter (for ports 0-3), and the FSIP8 has two serial port adapters (one for ports 0-3 and the other for ports 4-7). If one or more ports consume the full 6.132 Mbps bandwidth, then the remaining ports should be administratively shut down.

For G.703/G.704 support, you must order port adapters PA-7KF-E1/120= or PA-7KF-E1/75=. The G.703/G.704 cables must match the ohm rating for the port adapters. For example, PA-7KF-EI/75, the 75-ohm port adapter, uses the G.703/G.704 75-ohm cable, CAB-E1-BNC.

Except for G.703/G.704 port adapters, the cable connected to the port determines the interface type and mode. Cisco 7000 series and Cisco 7500 series serial cables supported by the FSIP are listed in the "Cables" chapter in this catalog. These cables must be ordered with the FSIP.

Note Because the FSIP uses a special high-density port that requires special adapter cables for each electrical interface type, we recommend that you obtain serial interface cables from Cisco.

FSIP port adapters are compatible only with the FSIP and SSIP. They are not compatible with VIP2 and Cisco 7200 port adapters.
