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.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 468 Access Endpoint 17 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. Valid entries Usage 01 through 44 (G3r) or 01 through 03 (G3si)First and second characters are the cabinet number A through EThird character is the carrier 01 through 20Fourth and fifth character are the slot number 01 through 04 (Analog TIE trunks) 01 through 31 (DS1 Interface ports)Six and seventh characters are the circuit number
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 469 Access Endpoint 17 Communication Type Name Enter an name for the endpoint. Width Only appears if the Communication Type field is wideband. This field cannot be blank. COR The COR is administered so that only an administered connection (AC) endpoint can be connected to another AC endpoint. COS The COS is administered (refer to ‘‘ Class of Service’’ on page 532) so that the use of the Call Forwarding All Calls feature for access endpoints is prohibited. Valid entries Usage voice-grade-data For an analog tie trunk access endpoint. 56k-data For a DS1 access endpoint enter as appropriate (64k-data is not allowed for robbed-bit trunks). 64k-data wideband For a Wideband access endpoint Valid entries Usage 2 to 31Enter the number of adjacent DS0 ports beginning with the specified Starting Port, that make up the WAE. 6 A width of 6 defines a 384 Kbps WAE. Valid entries Usage 0 to 95Enter the appropriate class of restriction (COR) number. Valid entries Usage 0 through 15Enter the appropriate COS number.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 470 Access Endpoint 17 TN 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 packValid entries Usage 1 through 20Enter the Tenant Partition number.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 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.

Enter the address of the destination access or data endpoint. This endpoint is the terminating party of the AC and need not be local to the switch on which the AC is assigned. The entry must be consistent with the local switch’s dial plan (that is, the first digits are assigned as an extension, feature access code, or trunk access code, or DDD Number). If a local extension is entered, it must be assigned to either an access or data endpoint. Abbreviated Dialing entries may be used in this field. Valid entries Usage Assigned access endpoint/data module extensionThe endpoint must be local to the switch on which the AC is administered. Nonsignaling DS1 trunk or analog tie trunk.

DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 474 Administered Connection 17 Name Authorized Time of Day Continuous The connection will be up all the time or re-established if the connection goes down. Start Days (Sun through Sat) These fields indicate only the days on which an attempt will be made to establish the AC and not necessarily the days it is active. A scheduled AC may be active over a number of days, and, in this situation, these fields should be used only to specify the days on which the AC starts and not other days on which the AC may be active. Only appears if the Continuous field is n. Start Time Only appears if the Continuous field is n. Valid entries Usage Up to 27 alphanumeric characters. Enter a short identification of the AC. Valid entries Usage y Indicates that the AC is continuous (that is, not scheduled to be active at a certain time). If y is entered, the seven Start Days and associated Duration fields do not appear. nDisplays the Start Days fields. Valid entries Usage yEnter y in each of the required days of the week fields to indicate that an attempt will be made to establish the AC. n Displays the day fields. Valid entries Usage 00:00 through 23:59 Enter the time of the day when an attempt should begin to establish a scheduled AC. The time is specified in two fields separated by a colon.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 475 Administered Connection 17 Duration Enter the period of time that the scheduled AC should remain active. This period is specified in two fields separated by a colon. The maximum duration is 167 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 000 through 167 For the hour field. 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.
DEFINITY ECS Release 8.2 Administrator’s Guide 555-233-506 Issue 1 April 2000 Screen reference 476 Alias Station 17 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). Retry Interval Auto Restoration Priority Enter a number that is to be used to determine the order in which ACs are to be established. Alias Station This screen allows you to configure the system so that you can administer new phone types that are not supported by your system software. This screen maps new telephone models to a supported telephone model. This mapping does not guarantee compatibility, but allows nonsupported models to be administered and tracked by their own names. Valid entries Usage 1 through 10An alarm generates on the first failure if this field is 1. Valid entries Usage 1 through 60Enter the number of minutes between attempts to establish or reestablish the AC Valid entries Usage yEnter y to indicate an attempt is to be made to reestablish an AC that failed. Auto Restoration is available only for an AC that is established over an ISDN Software Defined Data Network (SDDN) trunk group. A y in this field is ignored in all other situations. Valid entries Usage 1 through 81 is the highest and 8 the lowest priority
