The Mediant 2000 RTM includes a PSTN trunks and an Ethernet interfaces.
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 provided with a choice of rear panels (1-span, 2-span, 4-span, 8-span or
16-span).
Rear panel with two 50-pin female Telco connectors (DDK 57AE-40500-21D) (shown in Figure
2-3 ) is required for a gateway equipped with up to 16 E1/T1 spans. Rear panel with RJ-48c
connectors (shown in Figure 2-4 ) 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.
