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:

1Cable 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.

2Make 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).

3Repeat Step 2 for the remaining cards.

4When the last card in the daisy chain is reached, make no connection to the DB9 male connector labeled “P4” (away from MMI terminal).

5If 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.
