Extension
A display-only field showing the extension number as specified in the command line, or shows the next
available extension number if next was entered on the command line. This is the extension number
assigned to the nonsignaling trunk and used to access the trunk endpoint.

from this endpoint. Displays when the

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.

Usage
When unrestricted, only unrestricted transmission facilities (b8zs) 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 Wideband Access Endpoints, enter unrestricted.
When restricted, either restricted (zcs-ami) 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.
