Keying will prevent the NTDW61 circuit card from being inserted into this
slot.

on page 173.
Media Gateway Controller
The Media Gateway Controller (MGC) Card is designed to replace the
gateway functionality of the SSC. It does not function as a Call Server,
requiring a separate Pentium based Call Server to handle call processing
requests. The MGC Card replaces the SSC in the CPU card position of an
Option 11C cabinet or an MG 1000E chassis, both for upgrades and new
installations. The MGC Card Supports legacy backplane interfaces (DS30x,
CEMUX). Key features include:
• Increased Processing Power (10x over SSC)
• Increased memory capacity (128Meg vs SSC 32Meg)
• Standard Compact Flash used for permanent storage
• 2 PMC/PTMC Expansion Daughter board sites available
• Embedded L2 Switch supports enhanced dual homing
• Enables co-resident applications (Voice Gateway and Media Gateway
Controller)
DSP Daughterboards (optional)
Two optional DSP Daughterboards are introduced for the MGC Card, the
NTDW62AA 32-port DSP daughterboard and the NTDW64AA 96-port DSP
CAUTION — Equipment Damage
Do not insert the NTDW61 model of the
CP PM Signaling Server circuit card into any
slot of an IPE cube. Doing so may cause
electrical shorts on adjacent circuit cards.
