AJ 2885 features
The
AJ 2885
is a modem for the professional user. It encompasses a number of features that
place it above the rest. It includes features such as:
•
Configuration through front panel LCD and key pad: for synchronous application, the 2885
SDV can be fully set up from its user friendly front panel.
•
Busy-Out: Whenever modems are pooled, a faulty modem will lock-up the rest. The busy-
out, standard in the CXR modems lets the PBX pass onto the next modem without
upsetting the system.
•
Line Quality Testing: The modem can test a line at every call. If it finds it below standard, it
will hang-up and retry up to 5 times transparently to the user. This guarantees that you have
the most reliable connection every time on any type of infrastructure.
•
BERT: The modem can perform simple Bit Error Rate Tests between two CXR modems to
qualify the digital transmission of data.
•
ITU V.13: Half duplex operation.
•
10
Configurations
•
Unattended Automatic Dial Backup: If ever your Leased Line fails, the
AJ 2885
will back-up
onto the dial-up network. Not only that, it will continue to monitor the Leased Line until it is
operational and switch back automatically. This is called Intelligent Look-Back. Back-up
may be allowed and disabled over week-day and week-end periods.
•
Password Security: To change configuration of the modem, 2 levels of password security
are provided - User & Supervisor.
•
Connection Security: 4 levels of security are provided:
Answerback, i.e. where the far modem asks the calling modem for a password,
transparently to the user.
Pass Through Access, i.e. where the far modem asks the user for a password.
Automatic Modem Password Access, i.e. same as before but for synchronous
operation.
Call back, i.e. the far modem asks for a password from the calling modem and
hangs up. The far modem associates a telephone number with the password and
calls back the original calling modem.
•
5 different Statuses:
Modem Configuration.
Line, e.g. Xmit/Rcve levels, signal quality etc.
Line Error Statistics, e.g. for MNP or V42, the number of bad characters, bytes
frames etc.
Leased Line Statistics, e.g. connection & idle time etc.
Dial-Up Statistics, e.g. same as leased line with directory information etc.
This is but a short list. For full details, consult the Command Set Manual.
