M13 MULTIPLEXER

• Allows transmission of far end receive failure (FERF) and alarm indication

signal (AIS) under microprocessor control.

• Allows inversion of inserted F or M bits for diagnostic purposes.

• Demultiplexes a single M12 format DS2 bit stream into four DS1 bit streams.

• Detects per DS1 payload loopback requests encoded in the received C-bits.

• Allows per DS1 payload loopback to be activated or cleared under

microprocessor control.

• Performs required inversion of second and fourth demultiplexed DS1 streams.

E1 Functionality

• Multiplexes three 2048 kbit/s bit streams into a single G.747 format 6312

kbit/s bit stream.

• Inserts frame alignment signal and parity bit into transmitted 6312 kbit/s bit

stream.

• Allows transmission of remote alarm indication (RAI) and reserved bit (Set II,

bit 3) under microprocessor control.

• Allows inversion of inserted frame alignment signal for diagnostic purposes.

• Allows inversion of the C-bits in anticipation of remote loopback

recommendations.

• Demultiplexes a single G.747 format 6312 kbit/s bit stream into three 2048

kbit/s bit streams.
