Preparing Network Connections
For E1, four serial cables are available from Cisco Systems for use with the MIP. All three have
DB-15 connectors on the MIP end and either BNC, DB-15, Twinax, or RJ-45 connectors on the
network end. Figure 2-26, Figure 2-27, Figure 2-28, and Figure 2-29 show the E1 interface cables
(respectively).

Serial Connection Equipment
The FSIP supports synchronous serial connections at T1 and E1 speeds; the actual speed depends on
the type of electrical interface used, the distances the signals must travel, and the configuration of
other ports on the same FSIP module. In general, you should use EIA/TIA-232 for speeds of 64 kbps
and below, and use X.21, EIA/TIA-449, V.35, or EIA-530 for higher speeds. (See the section
“Replacing RSP7000 DRAM SIMMs” in the chapter “Maintenance.”)
