Circuit ID
Chapter 6. FRONT PANEL OPERATION
Appendix D. CARRIER ID (MetaCarrier®)
It is IMPORTANT to understand that Circuit ID and the MetaCarrier Custom
Message are two distinct features of the CDM-425. Read your documentation
carefully.
With Carrier ID Enabled, 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 Chapter 6.
FRONT PANEL OPERATION, Sect. 6.1.3.1 Screen Saver).
Enter a Circuit ID string of up to 40 character. You may use the following characters to compose
either string:
[Space] ( ) * + - , . / 0-9
and
A-Z.
Date and Time
•
Enter a time using HH:MM:SS format (where HH = hour [00 to 23], MM = minutes [00 to
59], and SS = seconds [00 to 59]).
