Technical Specifications
Issue 1 December 1997 10-5
EC-1 Low-Speed (BBG12 3STS1E) 10
■ Electrical Specification
The EC-1 low-speed interface transmits and receives a standard electrical
EC-1 signal as specified in
ANSI
T1.102-1993 (51.844 Mb/s rate, STSX-1
interconnect specification, B3ZS encoded and scrambled).
Line buildout is provisionable as follows:
— 734A/D: 0 to 450 ft.
— Mini-Coax (KS-19224, L2): 0 to 150 ft.
— 735A: 0 to 250 ft.
■ Format Specification
The EC-1 low-speed interface provides clear channel transport of any
STS-1 signal compatible with the electrical STS-1 interface specifications
in
ANSI
T1.102.
■ Alarm Thresholding
The following parameters are monitored at the EC-1 interface to the
STSX-1:
— LOS
— LOF
— LOP
— Line AIS
— B2 thresholding signal fail
— B2 thresholding signal degrade.
The alarm level for each of the monitored parameters can be provisioned for
CR, MJ, MN, or status. B2 signal degrade thresholds are user settable in the
range from 10
-6
to 10
-9
BER.
■ Performance Monitoring (see Table 10-14)
— EC-1 line performance monitoring.
