 NT5D11 and NT5D14 Lineside T1 Interface cards

After setting the dip switches and installing the lineside T1 card into the 
selected card slots, the lineside T1 card is ready to be cabled to the CPE or 
CSU equipment. Connections can also be made to the MMI terminal or 
modem (optional), an external alarm (optional), and other lineside T1 cards 
for daisy-chain use of the MMI terminal (optional). 

The lineside T1 card is cabled from its backplane connector through 
connections from the motherboard circuit card only (no cable connections are 
made from the daughterboard circuit card) to the input/output (I/O) panel on 
the rear of the IPE module. The connections from the lineside T1 card to the 
I/O panel are made with the NT8D81AA Tip and Ring cables provided with 
the IPE module.

Usually, the I/O panel is connected to the T1 link and other external devices 
through the NT5D13AA lineside T1 I/O cable. See Figure 29 on 

This cable consists of a 25-pair amphenol connector (P1) on one end which 
plugs into the I/O panel. The other end has 4 connectors: 

a DB15 male connector (P2) which plugs into the T1 line 

a DB9 male connector (P3) which plugs into an external alarm system 

a second DB9 male connector (P5) which connects to an MMI terminal 
or modem

a DB9 female connector (P4) that connects to the next lineside T1 card’s 
P4 connector for MMI daisy chaining

All lineside T1 connections can be made at the main distribution frame 
(MDF) if it is preferred to not use the NT5D13AA lineside T1 I/O cable at the 
I/O panel.
