The PA-MC-STM-1 enables service providers to use a single fiber-optic circuit to provision 63 E1s-E1s that normally require 63 separate copper pairs. The PA reduces wiring complexity, and, when spare capacity is available, it enables service providers to turn up new E1s without dispatching a technician to the router The STM-1 (Synchronous Transport Module level-1) is the SDH ITU-T fiber optic network transmission standard. It has a bit rate of 155.52 Mbit/s. Higher levels go up by a factor of 4 at a time: the other currently supported levels are STM-4, STM-16, STM-64 and STM-256.Above STM-256 wavelength-division multiplexing (WDM) is commonly used in submarine cabling

An E1 signal is 2.048Mbps. An STM-1 (Synchronous Transmission Module level 1) is an SDH (Synchronous Digital Hierarchy) signal which is 155.52 Mbps which is equivalent to an OC-3 (Optical Carrier level 3) signal, and has about the same bandwidth as 75 E1 signals or 100 T1 signals The figure-1 depicts E1-frame. E1 frame takes 8 bits from each of the 64 kbps channels one by one. It retransmits these channels at 2048 kbps.
