Technical Specifications
Issue 3 June 2001
10-3
— 613C (22 gauge): 30 to 655 ft.
— 1249-C (26 gauge): 30 to 450 ft.
â– 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.
â– 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.
â– Loopback
— Quad DS1 facility loopback (BBF3)
— Single DS1 facility loopback (BBF3B) (Release 13.0 and later).
â– 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)
