11.02Amplified Talk Path. Figure 7-39 provides a functional diagram of a two-CO line amplified con- ference connection (an R-TEC VFR5050 amplifier is used here). The talk path for the connection is as follows: outside party 1—public telephone net- work—CO, CKTX—STRATA DK16—PEKU, port A—into AMP, CKTA—Out AMP, CKT B—PEKU, port B—STRATA DK16—CO, CKTY—public tele- phone network—outside party 2. This path is two- way so when outside party 2 talks, the talk level is amplified in the reverse direction.

NOTE:

Only the outside party 1 talk path is amplified to/from a system telephone when it is con- nected into a two-CO line conference.

11.03Amplifier Requirements.

•Customer-supplied.

•Must be FCC-registered, Part 68, and provide automatic gain control.

•Requires two PEKU or PESU station ports (17 and 18).

•Refer to the amplifier manufacturer’s in- stallation documentation for amplifier grounding instructions.

11.04Installation. Connect a two-way amplifier to the STRATA DK16 system in accordance with the

following steps (see Figures 7-39 and 8-27).

1)At the main distribution frame (MDF), connect the voice pair (VT, VR, port A) of circuit 6 on the designated PEKU or PESU PCB to one input of the customer-supplied two-way am- plifier. In the example in Figure 7-39, this is CKTA (Central Office Side A) of the VFR5050.

2)At the MDF, connect the voice pair (VT, VR, port B) of circuit 7 on the designated PESU or PEKU PCB to the other input of the amplifier. In the Figure 7-39 example, this is CKTB (subscriber side B) of VFR5050.

3)Plug the amplifier’s power cord into the 117 VAC (standard) wall outlet.

4)Set the gain and other amplifier parameters options per the amplifier manufacturer’s in- stallation documentation.

5)Program the STRATA DK16 system as follows:

•Program 10-3:Enables the appropriate PEKU or PESU PCB ports for amplifier connection. Only enable the ports that will be connected with the amplifier(s).

•Program 15-5:Enables appropriate CO lines for tandem connection.

•Program 10-1:LEDs 19 and 20 must be ON.

•Program 10-2:LED 18 and 19 must be ON.
