INSTALLATION

3.8INSTALLING 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.
