DS2 Transmitter Section:
· Generates the required X, F, and M bits into the transmitted DS2 bit stream.
· Provides for transmission of far end receive failure (FERF) and alarm
· Provides optional automatic insertion of far end receive failure (FERF) on
M12 Multiplexer Section:
· Multiplexes four DS1 bit streams into a single M12 format DS2 bit stream.
· Performs required bit stuffing including generation and interpretation of C-
· Includes required FIFO buffers for rate adaptation in the multiplex path.
· Performs required inversion of second and fourth multiplexed DS1 streams
· Allows insertion and detection of per DS1 payload loopback requests
· Allows per tributary alarm indication signal (AIS) to be activated or cleared for
· Allows automatic tributary AIS to be activated upon DS2 out of frame.
Synchronous System Interfaces:
· Provides seven 8Mb/s H-MVIP data interfaces for synchronous access to all
Allows inversion of inserted F or M bits for diagnostic purposes.

the DS0s of all 28 T1 links or all timeslots of all 21 E1s. T1 DS0s are bundled
from four T1 links in sequential order (i.e. 1-4, 5-8, 9-12, 13-16, 17-20, 21-24,
25-28). In normal mode, E1 timeslots are bundled from 4 E1 links in
sequential order (i.e. 1-4, 5-8, 9-12, 13-16, 17-20 and 21 by itself). In G.747
mode, E1 timeslots are bundled from 3 E1 links in sequential order, spaced
by a reserved timeslot on every 4th frame (i.e. 1-3/X, 4-6/X, 7-9/X, 10-12/X,
13-15/X, 16-18/X, 19-21/X).
