Module Components
4.3.7.2 Zone 3 Rear Transition Module Data Connector (P32)
The P32 connector on the RTM connects to J32 on the MPCBL0020 Single Board Computer and is
used to route the T1/E1 signals from the PMC slots (on the SBC) to the RTM.
Table 11 provides the pinout of the P32 connector. AP1[x] designates T1/E1 signals that are routed
from PMC 1 while AP2[x] designates T1/E1 signals routed from PMC 2.
