into the terminal. So, the alpha capability is handled on a trunk line basis. There are two
common ways to do this.
One way is to dedicate a trunk line so it is used ONLY for alphanumeric entry. When a call
comes in, the terminal answers immediately with modem tones. This mode is set up in the
parameters for each line (see System Configuration Files in Series 2000 Paging Terminals
Installation and Maintenance for details).
The other way is to use a line for both ordinary paging and for alphanumeric entry. This
requires no special setup, and works as follows: when a call comes in, we wait for overdial
digits. We will wait for five seconds (adjustable). If we get no digits in this time, then we
bring up modem tones in case it is an alphanumeric device calling. So, users who are
dialing from a phone just overdial the pager number and page as usual. However, an
alphanumeric device calls, waits for us to answer with modem tones, then proceeds with
the alpha page.
Notes About Alpha
Adjustments
When using modem communications, the line levels and balance are much more critical
than they are for regular paging. For adjustment procedure, see Trunk Cards and
Connections in Series 2000 Paging Terminals Installation and Maintenance.
Alpha Device Setup
Program your alpha entry device with the phone number to call. For DID-type lines, this
would be the number that you chose for the Status A record (see above). For non-
dedicated overdial lines, this would just be the same number everyone calls to do paging
on that line. For dedicated overdial lines, it would be the number for that particular phone
line that goes to the dedicated alpha trunk line in the terminal.
Maintenance Port
The maintenance ports do not normally do alphanumeric paging. This applies to both the
Modem maintenance port and the Local Connect option serial maintenance port. These
ports are for maintenance use; you can use the ZlinkW Page command for test pages, but
this is too awkward for normal operator alpha paging.
All Lines
Make sure that all trunk lines you will be using for alpha are equipped with the alpha
option. This is especially true when you have multiple lines in a particular group of lines,
