Identifying MSDL's

The following illustrates the difference in CS1000E and CS1000M MSDL hardware. A CS1000E doesn't have a network shelf.

NT6D80 - (Core/Net) 4 ports for PRI D-Channel (DCH) and Application Module Link (AML). Port 0 can be used for SDI (TTY)
NTBK51 - 2 port daughterboard, mounted on either the NTAK09 1.5 DTI/PRI card or NTBK50 2 Mb PRI digital trunk card
NTDW79 - A UDT card has on-board DDCH/DCHI functionality (same as a NTBK51), use LD 96 commands with l s c

CS1000E (IPMG with NTBK51)

Loops assigned to PRI cards in Media Gateways
Single port MSDL hardware on each PRI card
