ap553DS0Format

Module: INNOVX-CORE-MIB

OID (symbolic): INNOVX-CORE-MIB::ap553DS0Format

OID (numeric): 1.3.6.1.4.1.498.22.1.1.6.1

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: Defines the DS0 base rate as either 56K or 64K bits per second. This object value, in conjunction with the ap553NumDS0s object value determines the LIU aggregate bandwidth. `nx64k' defines a DS0 data format as clear channel in which all 8 bits of the DS0 are used for data. `nx56k defines a DS0 data format as 7 bits for data, and 1 bit used for signalling information or unused and forced to marks.

The DSU will enforce an 8x(N+1) minimum ones density requirement when ap553NetLineCoding == `ami' and ap553DS0Format == `nx64k' and ap553DS0AllocationScheme == `consecutive'.

What is ap553DS0Format?

Defines whether each DS0 timeslot used by this unit's aggregate line carries data as clear-channel nx64k (all 8 bits used for data) or nx56k (7 bits for data, 1 bit for signaling); combined with ap553NumberOfDS0s this determines the LIU's total aggregate bandwidth, and an 8x(N+1) minimum ones-density rule applies when AMI line coding and consecutive DS0 allocation are also in use with nx64k.
