Procedure 12

Connecting two or more lineside T1 cards to the MMI terminal
Follow this procedure for connecting two or more lineside T1 cards to the MMI
terminal:
1 Cable the DB9 male 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.
2 Make the connection from the first card to the second card by plugging the
DB9 female connector labeled "P4" (away from MMI terminal) from the
first card into the DB9 male connector of the second card labeled "P5"
(towards MMI terminal).
3 Repeat Step 2 for the remaining cards.
4 When the last card in the daisy chain is reached, make no connection to
the DB9 male connector labeled "P4" (away from MMI terminal).
5 If two lineside T1 cards are located too far apart to connect the "P4" and
"P5" connectors together, connect them together with an off-the-shelf
DB-9 female to DB-9 male straight-through extension cable, available at
any PC supply store.
