4 a DB9 female connector (P4) that connects to the next Lineside
T1 card’s P4 connector for MMI daisy chaining
--End--
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 35
"Lineside T1 card - connecting two or more cards to the MMI" (page 202).
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:
Step Action
1 a DB15 male connector (P2) which plugs into the T1 line
2 a DB9 male connector (P3) which plugs into an external alarm
system
3 a second DB9 male connector (P5) which connects to an MMI
terminal or modem
4 a DB9 female connector (P4) that connects to the next Lineside
T1 card’s P4 connector for MMI daisy chaining
--End--
Cabling from the I/O panel at the Main Distribution Frame
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.
Procedure 12
Connecting to the MDF
Step Action
To make the connections at the MDF, follow this procedure:
1 Punch down the first eight pairs of a standard telco 25-pair
female-connectorized cross-connect tail starting with the first tip
and ring pair of the Lineside T1 motherboard card slot on the
cross-connect side of the MDF terminals.
2 Plug the NT5D13AA Lineside T1 I/O cable into this 25-pair
cross-connect tail at the MDF, regardless of the card slot
restrictions that exist from the vintage level of IPE or CE module
used. This connection can also be made at the MDF without
using the NT5D13 Lineside T1 I/O cable, by cross-connecting
according to the pinouts in Table 83 "Lineside T1 card -
backplane pinouts" (page 198).
