Installing the IC-T1V interface card cables
The PRI is usually connected to a PBX or switch—local exchange (LE). Type and pin outs of these devices vary
depending on the manufacturer. In most cases, a straight-through RJ-45 to RJ-45 can be used to connect the
PRI (see
table 37
on page 110 for IC-T1V card port pin-out listing) with a PBX. A cross-over cable is required
to connect to a NT2, as illustrated in
figure 76
.
