Access Endpoint
Issue 5 October 2002 595555-233-506
COS
The COS is administered (see ‘‘Class of Service’’ on page 672) so that the use of
the Call Forwarding All Calls feature for access endpoints is prohibited.
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.
ITC (Information Transfer Capability)
This field is used to determine the type of transmission facilities to be used for
ISDN calls originating from this endpoint. Displays when the Communication
Type field is
56k-data, 64k-data, or Wideband.
When adding an access endpoint with the ITC administered as unrestricted, its
associated port has to be a channel of a DS1 circuit pack with the Zero Code
Suppression field administered as B8ZS. If the port is not a channel of a DS1
circuit pack with its Zero Code Suppression field administered as B8ZS, the end
validation fails and the screen submission is rejected. The cursor is moved to ITC
with the following error message:
An unrestricted access endpoint can only be from B8ZS DS1
circuit pack.
When adding an access endpoint with the ITC administered as restricted, its
associated port can be a channel from a DS1 circuit pack with the Zero Code
Suppression field 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 not a channel of a
DS1 circuit pack with its Zero Code Suppression field administered as B8ZS, the
end validation fails and the screen submission is rejected. The cursor is moved to
ITC with the following error message:
An unrestricted access endpoint can use only B8ZS DS1
circuit pack
