The Dynetcom Dynaswitch� II is designed to provide
remote A/B switching capability for two Channels in a rack
mounted 1U Chassis. The unit can monitor selected circuits
for activity and respond with a variety of alarm and
switching actions depending on how the controller is
programmed. Switching can be manually controlled locally,
automatically controlled locally or controlled remotely.
Each chassis can be equipped with the capability
of switching any combination of RS232/V.24, RS530, or V.35
with using DB25 connectors, X.21 using DB15 connectors, G703
using BNC connectors or Ethernet, T1/E1, RS232/EIA 561,
using RJ-45 connectors. All industry standard products that
use DB25 or RJ-45 port connectors can be supported. The
RJ-45 and BNC module is available in both single or dual
bank versions.
Each Switching Module has a A/B toggle switch for local
switching and a red/green LED to indicate the A or B switch
position and has LED monitoring of RxD and TxD, a variable
carrier alarm, a reset, and an off switch.
The Dynaswitch� II incorporates a Master Switch
Control and Alarm Module and a Dynetcom MARC-12
Serial/IP Remote Control Module. Switching can be
accomplished locally using either the master A/B toggle
switch on the front of the unit or the individual channel
A/B toggle switches. Switching remotely can be accomplished
over a dedicated serial link, or though an IP network (such
as the Internet).
In common with all the Dynetcom line Mark II A/B
switching systems the switching modules feature latching
relays for clean physical-level circuit switching and
position retention in the event of power loss.
The Dynaswitch� II comes equipped with the Line
Activity Scanner (LAS) Feature, which provides the A/B
switch module with the capability to monitor selected
circuits for activity and be configured to generate alarms
and/or perform an appropriate switching action; e.g. alarm
and switch, alarm and email, alarm only, email and switch,
etc. Monitored lines (depending on interface type and pin
configuration) are: Data Terminal Ready (DTR) A or B,
Request to Send (RTS), Clear to Send (CTS), Data Carrier
Detect (DCD), and Data Set Ready (DSR) TD and RD.
Some of these devices are known as
Hadax, Dynatech, Spectron, VIR, or Eastern Research Digital
Patch Panels. Or Digital Switch Patching Systems.
