1:N Mode: (use with CAUTION!)
Disabled (Enable, Disable) (

)
For use when the unit is part of a 1:N redundant application (e.g., via a CRS-300 1:10
Redundancy Switch). Use the
▲▼ arrow keys to select 1:N Mode operation as
Enable or
Disable . Press ENTER .
When the unit is connected to a 1:N switch, a red LED located on the rear panel
labeled “1:N Active!” indicates that caution is required, as there may be DC
voltages and other control signals present on certain pins on the 25-pin ‘Data
Interface’ connector.
6.2.6.6 Utilities: Circuit-ID
Edit this Modem’s Circuit ID: (

)
----------------------------------------
Compose a Circuit ID string on the bottom line by using the
◄ ►
arrow keys to select the
alphanumeric character space to edit. Then, use the
▲▼ arrow keys to change that character.
You may use the following characters to compose a Circuit ID string of up to 40 characters in
length or a MetaCarrier Custom Message of 24 characters or less:
[Space] ( ) * + - , . / 0-9
and
A-Z.
Press ENTER once you finish composing the Circuit ID string. As created here, in addition to the
front panel VFD, the Circuit ID also appears in the title bar of compatible web browsers for easy
unit identification.
Proper composition of the Circuit ID string depends whether the Carrier ID
(MetaCarrier) feature operation is turned ON or OFF (see Sect. 6.2.6.3 Utilities:
CarrID):
1. With Carrier ID turned ON, the first 24 characters of the 40-character Circuit
ID are intended for and sent as the MetaCarrier Custom Message. While you
must limit your MetaCarrier Custom Message to 24 characters or less, the full
40 characters of the Circuit ID will display on the front panel screen saver
(see Sect. 6.1.3.1 Screen Saver).
2. With Carrier ID turned OFF, the Circuit ID full 40 character length is available
for creation of the unit identification label that displays on the front panel
VFD screen saver and the Web browser title care.
