Interface Connectors

The methods for providing network connection for
devices in the carrier are:
Via two 50-pin digital network or leased-line
interface connectors to the following:
— DDS (Digital Data Service)
— LADS (Local Area Data Set)
— Analog leased-line networks
Through Network Interface Modules (NIMs) to the
following:
— Dial network
— ISDN
— 2-wire switched 56 kbps
— 4-wire switched 56 kbps
Using one 50-pin connector on the T1 auxiliary
backplane for T1 CSUs or T1 DSUs/CSUs.

Digital or Analog Leased-Line
Network Interfaces
Use one of the following for the digital/analog
leased-line interfaces:
If a 50-pin cable is
attached to . . .
A 66A punchdown block
A RJ48T-type network
interface adapter cable,
feature 3600-F2-503,
which allows from 1 to 12
DDS circuits to be placed
on the 50-pin connector
An adapter cable, feature
3600-F2-503, to provide
8 keyed modular
connectors using
Pins 1, 2, 7, and 8
An adapter cable, feature
3000-F1-009, with eight
6-pin modular plugs

Then . . .
Hardwire the circuits to the
block.
Tell the service provider
that only the first 8 circuit
positions are used in each
50-pin connection. Do not
use a leased-line modem
in the same carrier half.
Connect the DSU to a
standard DDS network
interface (RJ48S); provides
a JM8-style leased-line
modem connection. Only
mix DSUs and leased-line
modems if the analog
leased-line network
interface is a JM8.
Only use for a
DDS/leased-line (Canada).
