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 “FSIP

Conﬁgurations” in the chapter “Maintenance.”)
