Modem Pool Group
There are two types of conversion resources for Modem Pooling. The first type, an 
integrated conversion resource, is a circuit pack that emulates a Trunk Data 
Module connected to a 212A-type modem. Two conversion resources are on each 
circuit pack.
The second type, a combined conversion resource, is a separate Trunk Data 
Module and modem administered as a unit. The Trunk Data Module component of 
the conversion resource may be either a Modular Trunk Data Module (MTDM) or 
7400A Data Module and connects to a digital port using Digital Communications 
Protocol (DCP); the modem connects to an analog port.

Valid entries Usage
-15
 to 3Enter the number for the loss/gain when the MFC port listens to 
the trunk port. Your switch listens with a range of -5 to -35 and

Valid entries Usage
-15
 to 3Enter the number for the loss/gain when the trunk port listens to 
the MFC port. The MFC port generates at -5 for MFC and -8 for 
MFE, and this field adds gain or loss to the starting value of -5.
