Technical Specifications
Issue 3 June 2001
10-3
— 613C (22 gauge): 30 to 655 ft.
— 1249-C (26 gauge): 30 to 450 ft.
■ Format Specification
The DS1PM low-speed interface can be provisioned for the following DS1
formats: clear channel (default), superframe (SF) as specified in
ANSI
T1.403-1989, or extended superframe (ESF) as specified in
ANSI
T1.403-1989. In the case of SF or ESF format selections, DS1
performance information is collected by monitoring the associated DS1
framing format.
■ Alarm Thresholding
The following parameters are monitored at the DS1PM interface:
— Loss of signal (LOS)
— Line coding violations (CV-L).
The alarm level for each of the monitored parameters can be provisioned to
CR, MJ, MN, or status. B8ZS and AMI coding violation failure thresholds are
user settable to 10
-3
or 10
-6
and in Release 8.0 and later releases 10
-7
or
10
-8
BER.
■ Loopback
— Quad DS1 facility loopback (BBF3)
— Single DS1 facility loopback (BBF3B) (Release 13.0 and later).
■ Performance Monitoring (see Table 10-23)
DS1 Path Parameters:
— Errored Seconds (ES-P)
— Severely Errored Second (SES-P)
— Unavailable Seconds (UAS)
— CV-P Coding Violations (Release 7.2 and later)
— CV-PFE Coding Violations (Release 7.2 and later)
DS1 Line Parameters:
— ES-L Errored Seconds (Release 7.2 and later)
