DESCRIPTION
The DS2172 Bit Error Rate Tester (BERT) is a software
programmable test pattern generator, receiver, and
analyzer capable of meeting the most stringent error
performance requirements of digital transmission facili-
ties. Two categories of test pattern generation (Pseudo-
random and Repetitive) conform to CCITT/ITU O.151,
O.152, O.153, and O.161 standards. The DS2172
operates at clock rates ranging from DC to 52 MHz. This
wide range of operating frequency allows the DS2172 to
be used in existing and future test equipment, transmis-
sion facilities, switching equipment, multiplexers,
DACs, Routers, Bridges, CSUs, DSUs, and CPE equip-
ment.
The DS2172 user programmable pattern registers pro-
vide the unique ability to generate loopback patterns
required for T1, Fractional–T1, Smart Jack, and other
test procedures. Hence the DS2172 can initiate the
loopback, run the test, check for errors, and finally deac-
tivate the loopback.
The DS2172 consists of four functional blocks: the pat-
tern generator, pattern detector, error counter, and con-
trol interface. The DS2172 can be programmed to gen-
erate any pseudorandom pattern with length up to 2
32–1
bits (See Table 5, Note 9) or any user programmable bit
pattern from 1 to 32 bits in length. Logic inputs can be
used to configure the DS2172 for applications requiring
gap clocking such as Fractional–T1, Switched–56,
DDS, normal framing requirements, and per–channel
test procedures. In addition, the DS2172 can insert
single or 10
–1
to 10
–7
bit errors to verify equipment
operation and connectivity.
