2 TELECOM SPECIFICATIONS COMPLIANCE
The DS26303 LIU meets all the relevant latest telecommunications specifications. Table 2-1 provides the T1
specifications and Table 2-2 provides the E1 specifications for the relevant sections applicable to the DS26303.
Table 2-1. T1-Related Telecommunications Specifications
ANSI T1.102–Digital Hierarchy Electrical Interface
AMI Coding
B8ZS Substitution Definition
DS1 Electrical Interface. Line rate ±32ppm; Pulse Amplitude between 2.4V to 3.6 V peak; Power level between
12.6dBm to 17.9dBm. The T1 pulse mask is provided that we comply. DSX-1 for cross connects the return loss is
greater than 26dB. The DSX-1 cable is restricted up to 655 feet.
This specification also provides cable characteristics of DSX-Cross Connect cable—22 AVG cable of 1000 feet.
ANSI T1.231–Digital Hierarchy–Layer 1 in Service Performance Monitoring
BPV Error Definition, Excessive Zero Definition, LOS description, AIS definition
ANSI T1.403–Network and Customer Installation Interface–DS1 Electrical Interface
Description of the Measurement of the T1 Characteristics—100
Ω, pulse shape and template according to T1.102;
power level 12.4dBm to 19.7dBm when all ones are transmitted.
LBO for the Customer Interface (CI) is specified as 0dB, 7.5dB, and 15dB. Line rate is ±32ppm.
Pulse Amplitude is 2.4V to 3.6V.
AIS generation as unframed all ones is defined.
The total cable attenuation is defined as 22dB. The DS26303 functions up to 36dB cable loss.
Note that the pulse mask defined by T1.403 and T1.102 are different—specifically at Times 0.61, -0.27, -34,
and 0.77. The DS26303 is compliant to both templates.
Pub 62411
This specification has tighter jitter tolerance and transfer characteristics than other specifications. The jitter transfer
characteristics are tighter than G.736 and jitter tolerance is tighter the G.823.
