Integrated Modem Pools
There are two primary types of Modem Pool conversion resources available: an
Integrated Pooled Modem and a Combined Modem Pool. The integrated TN758
Pooled Modem circuit pack contains two independent 300- or 1200-bps
conversion resources. Each conversion resource contains two interfaces to the
PBX digital network: an analog port and a digital port. The analog port is
connected through the PBX network to the analog line or trunk port containing the
analog modem signals. The digital port connects through the PBX network to the
digital line or trunk port in the call. The figure below shows a typical end-to-end
connection using a conversion resource on the integrated Pooled Modem circuit
pack.
