installation screws on each newly installed interface processor before you insert any additional
interface processors. These screws also prevent accidental removal, and provide proper grounding
and EMI shielding for the system.
FSIP Port Adapters, Interface Cables, and Connections
The universal port adapters and adapter cables allow eight interface ports on an FSIP, regardless of
the size of the connectors typically used with each electrical interface type. (See Figure 9.)
Figure 9
Port adapters are field-replaceable daughter boards mounted to the FSIP, and each provides two
high-density connectors for two FSIP ports.
All FSIP port adapters use an identical 60-pin, D-shell receptacle that supports all interface types:
EIA/TIA-232, V.35, EIA/TIA-449, X.21, and EIA-530. An exception to this is the E1-G.703/G.704
port adapter, which uses a 15-pin, D-shell receptacle.
FSIP Interface Cables
Each port requires a serial interface adapter cable that provides the interface between the
high-density FSIP port and the standard connectors that are commonly used for each electrical
interface type. Rate of data transmission depends on the type of electrical interface: EIA/TIA-232
for speeds of 64 kilobits per second (kbps) and below; X.21, EIA/TIA-449, V.35, or EIA-530 for
higher speeds.

20 Fast Serial Interface Processor (FSIP) Installation and Configuration
Always use the ejector levers when installing or removing processor modules. A module
Using the thumb and forefinger of each hand to pinch each ejector lever, simultaneously
push the top ejector lever down and the bottom ejector lever up until both are parallel to
the faceplate. (See Figure 8c.)
Tighten the captive screws on the top and bottom of the interface processor faceplate to
prevent the interface processor from becoming partially dislodged from the backplane
and ensure proper EMI shielding. (These screws must be tightened to meet EMI
specifications.)
To ensure adequate space for additional interface processors, always tighten the captive
