Rear Transition Module
The RTM includes PSTN trunks, an Ethernet interface and an optional RS-232 connector
(available only on the 1, 2 and 4-span configuration).
The Ethernet interface features dual 10/100 Base-TX, RJ-45 shielded connectors for (an
active / standby) redundancy scheme providing protection against the event of a failure.
The PSTN interface is available in 1-span, 2-span, 4-span, 8-span, or 16-span rear panels.
Rear panel with two 50-pin female Telco connectors (DDK 57AE-40500-21D) (shown in
Figure 4
) is required for a gateway equipped with 16 E1/T1 spans. Rear panel with RJ-48c
connectors (shown in
Figure 5
) is required for a gateway equipped with 1, 2, 4, or 8 E1/T1
spans. The physical difference between the 1-Span, 2-Span and 4-Span RTMs, and the 8-
span RTM is that the RJ-48c ports are depopulated correspondingly.
