ATT Definity Addendum 1 For Ds1, Dmi, Isdn Pri Instructions Manual

ADMINISTRATION OPTIONS AND REQUIREMENTS — GENERIC 27-63
Field 13Assigns whether a DS1 facility (translated in field 12) will be used as the primary or
secondary synchronization source to the switch. Field encodes and their descriptions
are:
0 Assigns that the facility is not used as a synchronization source
1 Assigns that the facility is the primary synchronization source
2 Assigns that the facility is the secondary synchronization source
NOTE: The primary must be administered before the secondary. The...

Field 14Field encodes and their descriptions are:
0 Assigns that the DS1/DMI-BOS channels can be used for both trunks and lines
(mixed); the latter is frequently called off-premises stations (OPS).
1 Assigns that the interface is used to provide DMI-BOS trunks. The DMI-BOS
trunk groups are defined using procedure 100, word 1 (encode 108 and/or 109).
DMI-BOS applications use the switchs DS1 to provide a high-speed multiplexed
data interface for...

ADMINISTRATION OPTIONS AND REQUIREMENTS — GENERIC 27-65
Field 15Some facilities require that the contents of the D-channel be inverted to guarantee that
the minimum ones density be maintained (that is, ZCS line coding is used). This field
shows whether the D-channel is inverted or not. Field encodes and their descriptions
are:
- (Dash) not applicable or ZCS line coding is translated in field 9. The dash is
appropriate for all applications of the ANN11 circuit pack. RBS does not use the
24th-channel to...

Field 18Loop length refers to the total cable distance between the switch and the NCTE, CDM,
BCM32000, DSX-1 cross-connect, and T1 office repeater. Traditional modules may
contain the ANN11 and/or ANN35 circuit packs. Both circuit packs contain DIP
switches for setting the compensation value [refer to table 3-1, System 85 Traditional
Module Equalizer Settings (Metallic Cable) ]. Therefore, software administration is not
applicable and the (–) should...

Field 20This display-only field serves to show which cables contain which synchronization
cables.
Procedure 262 Word 1: Additional DMI-MOS/ISDN-PRI Facility Options
Procedure 262 is used to administer the ANN35 and TN767 circuit packs. Figure 7-29, Procedure 262
Word 1: Additional DMI-MOS/ISDN-PRI Facility Options (Generic 2), depicts this procedure.½

Field 6Assigns this interface as the user (0) or the network (1) side. When connected to a
4ESS, the customer premises switch is always the user side. When not connected to a
4ESS (that is, when connected to another switch), one switch is the user side and the
other the network side.½

For MOS facilities (such as DMI-MOS and ISDN-PRI), each link must be segmented
into user and network sides. At a Generic 2, each MOS-based facility connected to...

Field 9The field accepts encodes from 0 through 255, which correspond to 1 second intervals
for a maximum elapsed time of 4 minutes and 15 seconds. The default value for this
T203 timer is 30 (30 seconds). This timer functions to monitor the facility data link
and specifies the maximum time allowed without frames being exchanged on a data
link layer connection.
Field 10The field accepts encodes from 0 through 255, which correspond to 0.1 seconds...

Procedure 262 Word 3: ISDN-PRI Codeset Map Assignments
Depending on the terminating switch it may be necessary to administer a Codeset Map Assignment and
convert from one codeset or codepoint to a different codeset or codepoint. This administration
assignment is required for ISDN-PRI links originating on a Generic 2 and terminating on a System 85
R2V4. Figure 7-31, Procedure 262 Word 3: ISDN-PRI Codeset Map Assignments (Generic 2), depicts½

Field 7Assigns whether hyperactivity management will be enabled for the ISDN-PRI link.
Hyperactivity is defined as erratic behavior by the D-signaling channel. Typically, a
hyperactive link will generate an excessive amount of meaningless traffic. Excessive
D-channel traffic may overload the module processor and degrade system performance.½
