Overview
The PmT1 and PmE1 is a single width PMC module designed to provide high-speed T1 and
E1 interfaces for PMC-compatible baseboards. The design is based on the Freescale™
MPC860P PowerQUICC™ microprocessor and the PLX Technology PCI9060ES bus interface
controller. The PmT1 has two standard landed T1 channels, and the PmE1 has two standard
landed E1 channels. An optional EIA-422 port is available.
