T1 connections
T1 signaling for all 24 channels is transmitted over P2 connector pins 1, 3, 9, and 11 as shown
in
Table 77: Lineside T1 card - NT5D13AA connector pinouts
male connector labeled "P2" into the T1 link. T1 transmit and receive pairs must be turned over
between the Lineside T1 card and CPE equipment that is hardwired without carrier facilities.
If the Lineside T1 card is connected through T1 carrier facilities, the transmit and receive pairs
must be wired straight through to the RJ48 at the Telco demarc, the CSU, or other T1 carrier
equipment. The T1 CPE equipment at the far end has transmit and receive wired straight from
the RJ48 demarc at the far end of the carrier facility.
External alarm connections
P3 connector pins 3, 4, and 28 can be plugged into any external alarm hardware. Plug the
male DB9 connector labeled "P3" into the external alarm. These connections are optional, and
the functionality of the Lineside T1 card is not affected if they are not made.
The MMI (described in detail in
Man-Machine T1 maintenance interface software
page 175) monitors the T1 link for specified performance criteria and reports on problems
detected.
One of the ways it can report information is through this external alarm connection. If
connected, the Lineside T1 card's microprocessor activates the external alarm hardware if it
detects certain T1 link problems that it has classified as alarm levels 1 or 2. See
T1 maintenance interface software
on page 175 for a detailed description of alarm levels and
configuration. If an alarm level 1 or 2 is detected by MMI, the Lineside T1 card closes the
contact that is normally open, and opens the contact that is normally closed. The MMI
command Clear Alarm returns the alarm contacts to their normal state.
MMI connections
P5 connector pins 2, 3, 5, 7 and 9 are used to connect the Lineside T1 card to the MMI terminal
and daisy chain Lineside T1 cards together for access to a shared MMI terminal. When logging
into a Lineside T1 card, "control 2" is asserted by that card, which informs all of the other cards
not to talk on the bus, but rather to pass the data straight through. The pins labeled "control 1"
are reserved for future use. As with the external alarm connections, MMI connections are
optional. Up to 128 Lineside T1 cards, located in up to 16 separate IPE shelves, can be linked
to one MMI terminal using the daisy chaining approach.
If only one Lineside T1 card is being installed, cable from the DB9 female connector labeled
"P5" (towards MMI terminal) to one of the COM ports on the back of any TTY, a PC running a
terminal emulation program, or a modem. For installations of only one card, no connection is
made to the DB9 male connector labeled "P4" (away from MMI terminal).
