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.
