6.1.8.2 DS-3/STS-1
Like the Plexus 9000 DS-1 interfaces, DS-3/STS-1 interfaces can be
provisioned for the following modes of operation: Primary Rate ISDN,
SS7 links/linksets, or as InterMachine Trunks (IMT).
Caution:
ISDN PRIs and SS7 signaling A-Links cannot be on the same
IOM.
CAS and SS7 signaling A-Links cannot be on the same IOM. The
maximum number of primary A-Links on an IOM is 2 and in a system is
34.
A-Links and Intermachine Trunks (IMTs) can be on the same IOM. IMTs
and PRIs can co-exist on an IOM. CAS and PRIs can co-exist on an IOM
with a maximum of 140 CAS DS1s and 84 PRIs.
There are different types of DS-3 IOMs. The triple DS-3 IOM, part
number 89-0365-A/B, provides three (3) DS-3s per module. The triple
DS-3/STS-1 IOM, part number 89-0365-C, provides three (3) DS-3s or
STS-1s per module. The octal DS-3/STS-1 IOM, part number 89-0382-A,
provides eight (8) DS-3s or STS-1s per module. The rear IOM interfaces
provide the DS-3/STS-1 terminations. Each triple DS-3 IOM terminates
three DS3 channels via two BNC connectors (one for transmit, one for
receive) per DS-3 for a total of six connectors. The octal DS-3/STS-1
IOM terminates eight DS-3/STS-1 channels via two BNC connectors per
DS-3/STS-1 for a total of sixteen connectors. Typically, the DS-3 cables
terminate at a DSX-3 cross-connect panel via BNC connectors. The cable
distance to the DSX-3 cross-connect panel cannot be greater than 450 feet.
