Access Manager 2000 User Manual

Alternate

Alternate channels are those which are assigned to a port
where every other channel carries user data, and the
channel before and channel after are unassigned. The DIU
fills each 8-bit word of the unassigned channel slots with
at least two ONEs, as outlined in AT&T TR 62421. (For
example, Port 1 = 1, 3 and Port 2 = 6, 8, 10.) Alternate
channel assignments allow the DIU 2130 and DIU 1130
to properly interface with the AT&T Accunet bundled
DS0 applications when unrestricted zeros applications are
required and B8ZS is not available.

Random

The random channels are those which are not assigned in
either a contiguous or alternate sequence. Some carriers
allow users to create bundled DS0 applications with
channels assigned in any order they choose (i.e., random
channel assignments).

To assign DSO channels:
