Universal Serial Port Adapters
The FSIP uses special universal serial port adapters and adapter cables to allow the high density
(eight) of interface ports on an FSIP, regardless of the size or form factor of the connectors typically
used with each electrical interface type. Figure 1-19 shows a universal port adapter with 60-pin
connectors that support all interface types. The adapter cable connected to the port determines the
interface type and mode.
The universal port adapters are field-replaceable daughter cards mounted to the FSIP, and each
provides two high-density connectors for two FSIP ports. (See Figure 1-19.) The 60-pin D-shell
receptacle supports EIA/TIA-232, V.35, EIA/TIA-449, X.21, and EIA-530.
Figure 1-19
The router (FSIP) end of all universal-type adapter cables is a 60-pin plug that connects to the 60-pin
port (receptacle) on the FSIP. The network end of the cable is an industry-standard connector for the
type of electrical interface that the cable supports: DB-25 for EIA/TIA-232 and EIA-530, DB-37 for
EIA/TIA-449, DB-15 for X.21, or a standard V.35 block connector. For most interface types, the
adapter cable for DTE mode uses a plug at the network end, and the cable for DCE mode uses a
receptacle at the network end. However, V.35 adapter cables are available with either a V.35 plug or
a receptacle for either mode, and EIA-530 is available only in DTE mode with a DB-25 plug.
Factory-installed 4-40 thumbscrews are standard at the network end of all cable types except V.35.
A metric conversion kit with M3 thumbscrews is included with each cable to allow connection to
devices that use metric hardware.
The FSIP is shipped from the factory with two or four dual-port adapters installed. Additional port
adapters are available as spares so that you can replace one that fails; however, you cannot upgrade
a four-port FSIP to an eight-port by adding port adapters. (The four-port FSIP is manufactured with
only one four-port module and processor.)
For port adapter replacement instructions, refer to the section "Replacing Serial Port Adapters" in
the chapter "Maintenance." The appendix "Cabling Specifications" provides adapter cable pinouts;
however, 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 the factory.
E1-G.703/G.704 Port Adapter
The FSIP E1-G.703/G.704 interface connects Cisco 7000 series routers with 2.048-Mbps leased line
services. The interface eliminates the need for a separate, external data termination unit to convert a
standard serial interface (such as V.35) to a G.703/G.704/G.732 interface.

Conn (connected or loopback)—On both DTE and DCE interfaces, this LED is on to indicate
normal operation: the FSIP is properly connected to the external device, and TA (DTE available)
and CA (DCE available) are active. When this LED is off, the FSIP is in loopback mode or is not
connected to the network or external device.
