ADMINISTRATION OPTIONS AND REQUIREMENTS — GENERIC 27-53 GENERIC 2 Depending on whether the switch provides private network ISDN service or public network ISDN services, whether the switch functions as an endpoint or as a tandem node, will determine whether other features should be administered before ISDN-PRI. Primarily, these other features include tandem tie trunk access, trunk-to-trunk calling, and miscellaneous trunk restrictions. When applicable, these features are administered with procedures 275,...

Field encodes and their descriptions are:½ — 0 1(Dash) required when ISDN is not provided. Current policy is to always ship ISDN-PRI software with the switch. However, the administration software still provides the option to assign this software as unprovided. Must be translated when ISDN is provided but disabled.

ADMINISTRATION OPTIONS AND REQUIREMENTS — GENERIC 27-59 Field 7If field 14 is defined as non-ISDN (0, 1, or 2) this field is equivalent to the Per- Channel Signaling and common channel signaling options used with System 85 R2V4. However, the terms have been changed to facility associated signaling (FAS) and NFAS.½ If field 14 is defined as ISDN (5), this field is used to specify the method used to construct signaling bits for each DS0 B-channel. The 23B + 1D option is also called FAS. If this interface...

Field encodes and their descriptions are: l Zero Code Suppression (ZCS) l Bipolar 8 Zero Code Suppression (B8ZS). The ZCS line-coding format (restricted) scans each byte for the all-zeroes octet and, on detecting this bit sequence, substitutes a one for the zero in bit position 2. The ZCS format is the most common...

ADMINISTRATION OPTIONS AND REQUIREMENTS — GENERIC 27-61 Field 10This option enables (1) or disable (0) collection of slip data to support excessive slip rate based on switching between the primary, secondary, or internal high-accuracy clocks. The decision to switch from one source to the other is normally based on an internal slip count calculation (software record). However, hardware events (such as primary link failures) may take precedence over any software controls.½ ½ ½ Slips are caused by...

7-62ADMINISTRATION OPTIONS AND REQUIREMENTS — GENERIC 2 Field 11Offers the options external loop not available (0) or available (1). The external loop available option should be selected only when demand diagnostic maintenance is done and then only after the interface has been busied out. This option is used with procedure 620, test 2, to extend the range of the test to include the network channel-terminating equipment (NCTE) and the connecting facility (any external equipment to the point of the DS1...
