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.
