Trunk Cards and Connections
74 025-9035AA
Model 2200 Backplane TELCO Pinouts (702-9071 Rev C - J19)
1
“-” means no connection.
2
“Radio” means that the signal is used by radio card slots.
3
The signal names ending in “A” are used by the single trunk card 702-9037. The dual trunk card
702-9117 uses signals ending in “A” for trunk A and signals ending in “B” for trunk B. The single
trunk card 702-9037 has no connections to any signals ending in “B”. For example, Signal “RING
10A” is a telco Ring signal from a trunk card plugged into slot number 10. If that card is a dual
trunk, the Ring signal is for trunk A on the dual trunk.
4
Connector J19 serves trunk cards plugged into card slots 7 through 11. This means five telco lines
if the cards are single 702-9037s, ten telco lines if the cards are dual 702-9117s or six to nine if using
a mixture of single and dual trunk cards.
5
The table shows the pins in numeric order, as they appear when looking directly at the connector.
When looking at them on a punch-down block, you need to flip the left and right halves of the table,
as the first pin on a punch-down block is pin 26, the second pin is 1, etc. Refer to the punch-down
block diagram on page 129.
