3.8 INSTALLING THE TPIM RI/RO MODULES
TPIMs provide RI/RO trunk port connections that support various
media for trunk cabling. You can attach different media types at the
Ring-In port and Ring-Out port. For example, you can insert a
TPIM-T1 as the Ring-In port and a TPIM-T4 as the Ring-Out port.
The following sections explain how to set the Phantom Switch, set the
RI/RO Switch, install the TPIM to the TRXI, and attach segments to
the TPIM.
Prior to connecting trunk cabling to the TPIMs, check the connectors
for proper pinouts. Table 3-1 provides a cross-reference of pinouts for
TPIMs used for Ring-In or Ring-Out applications.
