Configuring Trunk Cards (702-9037 and 702-9117)

(If a new card was added, Zetron will need to change terminal configuration files

for the card to work.)

Switch Settings

The switches on the single or dual trunk card should be set to match the card cage slot

number that the card is installed in. Revision D and later dual trunks may be addressed

above 15 by removing JP5. This adds 16 to the switch address. Telephone trunk cards may

be installed into slots 7 through 16 (on Model 2200), slots 4 through 13 (on Model

2200EX), or slots 6 through 10 (on Model 2100). Please see Table 6 for the switch

settings.

Jumper Matrix Settings

On each telephone interface card (702-9037 Trunk or 702-9117 Dual Trunk), the

configuration jumpers have been unified onto small daughter circuit cards named

“MATRIX”. To make the telephone interface operate properly, the matrix plug for every

telephone line must be in the correct position, and the software must be configured to

operate the card properly. The matrix card completes the proper electrical paths for the

different kinds of telephone interfaces (DID, End-to-End, and so forth). It also presents an

identification that the Trunk software can read and compare to the programmed Line

Type. A trunk card will refuse to operate if the hardware matrix plug and the software

Line Type disagree. (See System Configuration Files on page 217 for information on how

to set the Line Type).
