7798 I/SITE LAN 19
A pager differs from a beeper in that the pager sends a string of characters after a 5-
second period of silence. Also, beepers never use the semi-colon in their call string, while
digital pagers always require the semi-colon at the end of their call string. It is important
that you be familiar with the your pager service and phone system so that you know of
any specific characters that may be required to place a successful call. For example, if you
were to enter a phone number for SWB MobileComm pagers in a 78061 Tap emulation,
using an ITT System 3100 PBX you would use the following format.
T9W8172731511#@123456;
The “T” at the beginning of the character string initiates tone dialing, the 9 obtains an
outside line. The “W” causes the Tap to wait for the modem to receive a dial tone before
dialing the pager service phone number. At the end of the phone number is a # sign that
causes this PBX to perform speed dialing, eliminating any unwanted delays. The @ char-
acter causes the 78061 Tap emulation to listen for a 5-second period of silence and then
sends the code that will display on the recipients pager. The semi-colon causes the Tap to
signal the modem to immediately go on-hook, ending the call.
If your telephone system has no speed dial function, but has a period of silence exceeding
five seconds before the connection is made, add additional @ characters or commas to
prevent the Tap from prematurely sending the pager code.
If the number being dialed is really a pager system (particularly a digital pager system),
the modem should be initialized with an X2 command. This will cause the modem to
ignore at least some of the tones presented by the digital pager system (that may be inter-
preted as busy) when the call is successful.
Note: Some experimentation may be required to find the proper combination of characters to
make the pager call successful.
I/SITE LAN Operation
Communication Ports
There are three communication ports on the I/SITE LAN board, and an optional
controller LAN communication board that can be added as a plug-on board. All connec-
tions to the LAN, modems, serial printers, and external PCs are made using these ports.
See
Figure 2 on page 4 for port locations.
The RS232 serial port (P3) provides access to external PCs, serial printers, and asynchro-
nous modems. The ten-conductor ribbon connector (P4) and direct-wiring terminal
block (TB4) are the same communication port and provide connections for an external
synchronous or asynchronous modem. The RS485 port (TB2) provides connections for
the sub-controller LAN. Refer to “Installation Procedures” on page 8 for instructions on
connecting to these communication ports.
Communication LEDs
The I/SITE LAN provides one bank of LEDs along the right edge of the board (see
Figure 10 ) that show the status of communication in the I/SITE LAN and other informa-
tion. The I/SITE LAN uses the 10-segment LED indicators at U22.
