Section 1
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.
COMPONENTS AND FEATURES
The following is a brief summary of the PmT1 and PmE1 hardware components and fea-
tures:
CPU: The CPU for the PmT1 and PmE1 is the Freescale MPC860P PowerQUICC 32-bit micropro-
cessor chip running at 80MHz. See Chapter 3 for processor features.
RAM: The PmT1 and PmE1 module is populated with 16 megabytes of 32-bit wide DRAM.
Flash: The PmT1 and PmE1 module has a 32-pin PLCC flash socket with a 512-kilobyte flash capac-
ity.
Serial I/O: The PmT1 and PmE1 module has two EIA-232 I/O ports implemented with two serial man-
agement controllers (SMCs). If the second E1 channel is not required, the PmE1 can be fac-
tory configured to additionally provide a single EIA-422 serial port.
T1E1: The PmT1 is factory configured to support the T1 channel using the Dallas Semiconductor
DS2151Q controller. The PmE1 is factory configured to support the E1 channel using the
Dallas Semiconductor DS2153Q controller.
PCI Bus: The PLX Technology PCI9060ES controls the Peripheral Component Interconnect (PCI) bus.
The PmT1 and PmE1 modules appear as peripheral cards to PCI.
