A Screens Reference
When adding an access endpoint with the ITC administered as restricted, its
associated port can be a channel from a DS1 circuit pack with Zero Code Suppression
administered as zcs or b8zs.
For an existing access endpoint, ITC can only be changed from restricted to
unrestricted if its associated port is a channel of a DS1 circuit pack with its Zero Code
Suppression field administered as b8zs. If the port is on a channel of a DS1 circuit
pack with its Zero Code Suppression administered as zcs or b8zs, the end validation
fails and the form submission is rejected. Without this end validation, a user could
administer an access endpoint as unrestricted when in fact it is restricted, that is its
associated port is a member of a DS1 circuit pack that uses ZCS data transmission.
DTE/DCE Designates the interface defined by this data module as data terminal equipment or
data communications equipment.

Use restricted except for wideband endpoints.
For unrestricted, only unrestricted
transmission facilities (b8zs and hdb3) will be
used to complete the call. An unrestricted
facility is a transmission facility that does not
enforce 1’s density digital transmission (that is,
digital information is sent exactly as is).
For restricted, either restricted (ami-zcs or
ami-basic) or unrestricted transmission facilities
is used to complete the call. A restricted facility
is a transmission facility that enforces 1’s
density digital transmission (that is, a sequence
of eight digital zeros is converted to a sequence
of seven zeros and a digital one) via zcs coding
on DS1 circuit pack.
