Amplifier Requirements; Station Message Detail Recording (Smdr) Printer/Call Accounting Device Options - Toshiba Strata DK 280 Installation Manual

Note:
Only the outside party I talk path is amplified
to/from a system telephone when it is
connected into a two-CO line conference.
6.6.1 Amplifier Requirements
H Customer-supplied (four maximum).
n Must be FCC-registered, Part 68, and provide
automatic gain control.
n Each amplifier requires two PEKU station ports.
H Refer to the amplifier manufacturer's installation
documentation for amplifier grounding instructions.
,
Installation: Connect a two-way amplifier to the Strata
DK280 system in accordance with the following steps
(see Figures 6-19 and the Amplified Two-CO Line
Conference wiring diagram in Chapter 7-Wiring
Diagrams).
1.
At the main distribution frame (MDF), connect the
voice pair (VT, VR, port A) of Circuit 2 on the
designated PEKU PCB to one input of the
customer-supplied two-way amplifier. In the
example in Figure 6-19, this is CKTA (Central
Office Side A) of the VFR5050.
2.
At the MDF, connect the voice pair (VT, VR, port
B) of circuit 3 on the designated PEKU PCB to the
other input of the amplifier. In the Figure 6-19
example, this is CKTB (subscriber side B) of
VFR5050.
3. Plug the amplifier's power cord into the 117VAC
(standard) wall outlet.
4. Set the gain and other amplifier parameters
options per the amplifier manufacturer's
installation documentation.
5.
Program the Strata DK280 system as follows:
n
Program
lo-3-Enables the appropriate
PEKU PCB ports for amplifier connection.
Only enable the ports that will be connected
with the amplifier(s).
n
Program
15~5-Enables appropriate CO lines
for Two-CO line tandem connection.
n
Program
IO-I-LEDs 19 and 20 must be ON.
n
Program
IO-2-LED 18 must be ON.
Note:
LED 19 in Program lo- 1 should be ON if it is
certain that an amplifier will always be
available for two-CO line conference
connections (four maximum, simultaneously).
If this LED is ON and a two-CO-line
connection is established without an external
amplifier, the Strata DK280 station may be
unbalanced and receive a hum noise. LED 19
provides additional station amplification when
external amplifiers are switched into two-CO
line connections.
6.7 Station Message Detail Recording
(SMDR) Printer/Call Accounting
Device Options
An SMDR printer or call accounting device may be
connected to the system to provide a hard-copy record
(Figure 6-20 and 6-21) of station activity. The Strata
DK280 system can record incoming, outgoing, and
transferred calls, as well as Account Code entries. Call
record data is printed out at the completion of each
eligible call. SMDR format is ASCII-formatted, 8-bits,
no parity, l-stop bit. PIOU/PIOUS will be 300 or 1200
bps (see Chapter 4-Printed Circuit Boards) and RSIU
or RSIS can be 1200-9600 bps (see Program 76).
Program SMDR with Program 60-The SMDR port
will be active only on the PIOU or PIOUS with the
lowest Program 03 code (41, 42, or 43). or the RSIU
or RSIS Port programmed with code x2 in
Program 76-l.
Note:
If PlOWPIOUS and RSIWRSIS are assigned L
as SMDR simultaneously in programming,
RSIU/RSIS will operate as SMDR-not
PlOWPIOUS. A display of the customer data
base (Figure 6-22) can also be printed using
the SMDR RS-232 port by running Program
97.
SMDR will send out special names for the following
types of calls:
n MSS: Prints on Direct Inward System Access
(DISA) and External Call Forward calls to stations
(see Note 2).
n MODM: Prints on calls to the RMDS or IMDU
remote maintenance modem (Station #I 9).
n DISA: Prints on DISA and External Call Forward
calls in which CO lines are accessed for trunk-to-
trunk outside calling.
