Access Endpoint
This screen administers Access Endpoints and Wideband Access endpoints.
NOTE:
You can administer Wideband Access Endpoints only if, on the 
System-Parameters Customer-Options screen, the Wideband Switching field 
is 
y.
An Access Endpoint is a nonsignaling trunk that neither responds to signaling nor 
generates signaling. Access Endpoints eliminate the need to dedicate an entire 
trunk group for the access of a single trunk by providing the capability to assign 
an extension number to a single trunk. An Access Endpoint can be specified as the 
Originator or Destination endpoint of an administered connection.
A Wideband Access Endpoint (WAE) is an endpoint application connected to 
line-side non-ISDN T1 or E1 facilities and, like Access Endpoints, have no 
signaling interface with the system. For information on endpoint applications 
connected to line-side ISDN-PRI facilities, see ‘‘
PRI Endpoint’’ on page 853.
The WAE is defined by a starting port (DS0) and a width specifying the number of 
adjacent nonsignaling DS0s (positioned within a DS1 facility) that make up the 
endpoint. This width may be between 2 and 31 adjacent DS0s.
NOTE:
Access Endpoints and Wideband Access Endpoints consume the same 
resources that trunks use. Thus, the sum of Access Endpoints and trunks 
cannot exceed the maximum number of trunks available in your system 
configuration.

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.
(Starting) Port
Enter seven characters.
For example, 01A0612 is in cabinet 01, carrier A, slot 06, and circuit number 
(port) 12.
NOTE:
For Wideband Access Endpoints, analog tie trunks cannot be used and the 
DS1 Interface circuit pack, Version C or later, must be used.
The DS1 circuit number corresponds to the channel that will carry the data traffic. 
Channels 1 through 31 (DS1 Interface only) or channels 1 through 24 (DS1 Tie  
Trunk, DS1 Interface, or DS1 Interface (32)  circuit packs) may be used when the 
DS1 Signaling Type field is 
robbed-bit or isdn-ext. For Common Channel or 
ISDN-PRI signaling, channel use is limited to channels 1 through 30 (DS1 
Interface  circuit pack only) or channels 1 through 23 (DS1 Interface (32)  or DS1 
Interface ). A channel can be administered as an access endpoint regardless of the 
DS1 signaling type.

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

471 Administered Connection 
17
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.
Administered Connection
This screen assigns an end-to-end Administered Connection (AC) between two 
access endpoints or data endpoints. The AC is established automatically by the 
system whenever the system restarts or the AC is due to be active. Refer to 
‘‘
Administered Connections’’ on page 1133 and ‘‘Access Endpoint’’ on page 467 
for additional information.
Valid entries Usage
unrestricted
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.
restricted 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.

hours and 59 minutes (that is, 1 minute less than 1 week). Only appears if the 
Continuous field is 
n.
Miscellaneous Parameters
Alarm Type
Enter the type of alarm to be generated if the AC cannot be initially established, or 
fails and cannot be reestablished, and the number of consecutive failures equals 
the alarm threshold. All AC alarms and the errors that caused the alarms are 
recorded in the system’s alarm and error log. In addition, a status lamp associated 
with an attendant console or phone feature button (ac-alarm) may be used to 
indicate the AC alarm.
Valid entries Usage

00 through 59For the minute field.
Valid entries Usage
major
Failures that cause critical degradation of service and require 
immediate attention.
minorFailures that cause some degradation of service, but do not 
render a crucial portion of the system inoperable. This 
condition requires action, but its consequences are not 
immediate. Problems might be impairing service to a few 
trunks or stations or interfering with one feature across the 
entire system.
warning  Failures that cause no significant degradation of service or 
failures in equipment external to the system. Warning alarms 
are not reported to the attendant console or INADS.
noneThe alarm notification may be disabled for this AC.

Alarm Threshold
Only appears if an entry in the Alarm Type field is other than 
none. Enter the 
number of times an attempt to establish or reestablish an AC must fail 
consecutively before an AC alarm generates. (an alarm will be generated after the 
fourth retry has failed, thus, with the retry interval of 2 minutes, an alarm will be 
generated approximately 8 minutes after the first failure occurs).
