COMM-WATCH®

Remote T1 Monitor & Alarm

Specifications

Contact Electrodata at 1-800-441-6336
COMM-WATCH® is a full-featured, yet affordable remote monitor and alarm instrument for T1 data communications. COMM-WATCH acts as a sentinel for faults and errors on T1 lines. Reliable and vigilant, it monitors both the receive (Network) and transmit (Site) sides of the T1 circuit. It reports failures or alarm conditions to off-site locations and provides the information required to determine whether a fault is network related or is caused by on-site equipment.

Frequently Asked Questions

 

Who needs the COMM-WATCH?

Anyone dependent on a T1 network without full-time service personnel at each remote location. Prime examples are: the service providers themselves (telcos and CAPs), large private networks (investment companies, utilities, etc.), and wireless service providers.

What does COMM-WATCH do?

It monitors both the received signal from the network and the transmitted signal from the remote site for any indication of impaired performance or failure. It then stores this information in "bins" of 15 minutes for the last 24 hours and 1 hour bins for the last 7 days. In addition, it records up to 200 specific events with precise date and time information. Finally, COMM-WATCH compares these events to specified thresholds and places alarm calls when the thresholds are exceeded.

How do I get my pay-back for a COMM-WATCH investment?

Three ways: First through reduced service costs as a result of knowing , in advance, which is at fault, the network or the site. With this information, the proper service team, and only that team, is dispatched as soon as the fault occurs. Second, COMM-WATCH retains the network performance information needed to support/refute claims for rate adjustments. And last but not least, network performance and up-time are improved through rapid fault detection and isolation.

Do you still need COMM-WATCH when the CSU or other terminating equipment has statistics storage and reporting capability?

Yes, any active device may be the cause of the failure and unable to report properly. The COMM-WATCH passively "watches" the T1 circuit at the demarcation point between the service provider and the end-user. The connection to the T1 is through a high impedance to eliminate even the small chance that the COMM-WATCH could cause a failure.

Are separate telephone connections required for each COMM-WATCH, when a site has multiple T1s?

No, at sites with multiple T1's, multiple COMM-WATCH units can be connected together and share common communication links.

Can I have a back-up number called if the primary does not answer?

Yes.

Can I have a back-up alarm notification in the event of simultaneous failures on both the T1 and my telephone line?

Yes, COMM-WATCH supports two alarm communication lines in any combination of POTS (plain-old-telephone-service), wireless, or RS-232 connections.

Can I have COMM-WATCH call a pager and a network management system (NMS)?

Yes, COMM-WATCH supports a variety of alarm notification capabilities including alpha/numeric pagers, NMS systems, personal computers and simple printer logs.

How do I make changes in the "field" as my requirements change?

The COMM-WATCH can be provisioned remotely or via a local RS-232 connection. In addition, Electrodata will support remote upgrades of system software via OnCall® using a simple modem/ telephone connection.

Can the COMM-WATCH use 24 vdc power?

Yes, there are a variety of options for powering the COMM-WATCH including 24 vdc, -48 vdc and 120 vac.

Why do PCS systems have special needs?

PCS will depend on leased T1 communications to Base Transceiver Sites (BTS) and there will be approximately ten times the number of BTS's as current "cell sites". For PCS, the system will literally "live or die" on the performance of the leased T1 lines. Most BTS locations will not have a POTS circuit available and COMM-WATCH's ability to use a wireless connection to the next BTS location becomes a critical capability.

Don't many sites already have remote diagnostic capability?

Yes, but these sites do not have the ability to isolate between the leased T1 and the CSU during a land-line communications failure.
