DMC Faceplate cables
The faceplate cables form the 20 Mb/s bus that connects all DMCs in a DECT
system. The
faceplate cables meet the standard for Unshielded Twisted-Pair category of performance 5
(UTP CAT 5).
Signaling and PCM are sent to all DMCs over the faceplate cables, allowing a DMC8 to pass
a call to another DMC8.
The following faceplate cables are used in DECT systems:
1. DMC to DMC faceplate cable (NTCW11AA)
The cable extends the 20Mb/s bus to all DMCs.
2. DMC to DMC-E faceplate cable (NTCW11BA)
The DMC to DMC-E cable extends the 20Mb/s bus past the XPEC card in the IPE
shelf.
3. DMC bypass faceplate cable (NTCW11CA)
The DMC bypass faceplate cable bypasses DMCs to be inserted in or removed from
an operational DECT system.
4. DMC faceplate termination (NTCW11DA)
The DMC faceplate termination balances the impedance at either end of the 20Mb/
s bus.
5. DMC-E to DMC-E intershelf faceplate cable (NTCW11EA)
This faceplate cable connects DMC-Es in two shelves or two cabinets.
