ming.

11 OPTION INTERFACE UNIT (QSMU)

11.00 General

11.01The QSMU provides a circuit interface with peripheral options.

11.02The QSMU is shown in Figure 4-13.

11.10QSMU Hardware Options

11.11The QSMU supports the following STRATA DK8 external hardware options:

•SMDR output or TTY (maintenance) port two- way interface.

NOTE:

Refer to Peripheral Equipment Installation, Section 100-816-207, for installation of SMDR and the Remote Maintenance Section 100- 816-600 for TTY.

11.20QSMU Configuration

11.21The QSMU must be configured for operation with the appropriate external hardware: either an SMDR printer or call accounting device; Remote

Maintenance Terminal (TTY) or modem; and in System Prograrm 10-3:

•LED 04 ON — TTY

•LED 04 OFF — SMDR

11.30QSMU Installation Procedure

11.31Install the QSMU in accordance with the following steps (See Figure 4-7):

1)Remove the PCB from its protective packag- ing.

2)Ensure the QSMU has been configured for the appropriate program options (refer to Para- graphs 11.10 and 11.20).

3)Slide the QSMU under the "System Frame Ground Bar", align and insert QSMU connec- tor J2 into motherboard connector J20, ensur- ing the side of the QSMU with the modular connector goes on the right side. (The QSMU is not silkscreened “➝ RIGHT”.) Apply firm, even pressure to ensure proper mating of connectors. Make sure the edge of the QSMU opposite connector J2 snaps firmly into the standoffs on the KSU motherboard.
