Remote T1 Monitor & Alarm
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.

Asked Questions about COMM-WATCH.
COMM-WATCH has MANY unique features:
The primary benefit of using COMM-WATCH in your network is reduced cost.
Substantial savings are achieved through:
Supports both wireless and wire-line telephone connections for alarm communication
Stores data in 15 minute windows for 24 hours, 1 hour windows for 7 days,
and continuously until reset.
Date and time stamps up to 200 definable events
Supports primary and secondary alarm communication lines
Provides charging current for wireless telephone batteries
Windows®compatible software provided
Variable alarm thresholds
Programmable alarm messages and telephone numbers
Multiple units interconnect to monitor sites with more than one T1 circuit
High impedance connections ensure that the COMM-WATCH itself
does not cause a network failure.
COMM-WATCH quickly pays for itself and continues to save you time and money!
Reduced downtime due to rapid fault isolation
Greatly reduced labor costs due to more accurate dispatch
Identification of "time of day" related failures
Verification of network failures for "rate adjustments"
Warning of impending failure as a circuit degrades

a list of Frequently Asked Questions regarding the COMM-WATCH.
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?
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
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.
