M9456 Simultaneously Switches Six PRI Channels to A or B Output Devices with No Power Required

March 9, 2009




Electro Standards Laboratories (ESL), Cranston, RI, has just announced the Model 9456 Six-Channel RJ45 A/B Switch.  This network switch allows access to two separate Output devices, A or B, through a device connected to the Common port for each of the switch’s six Primary Rate Interface (PRI) Input channels.


The Model 9456 requires no power, allowing users to manually switch all six PRI channels simultaneously between A and B positions via one knob located on the front of the unit.   This 6-channel AB switch utilizes a high quality sealed switch mechanism with self-wiping contacts and is enclosed in a rugged all-aluminum 1U rackmount.  All eighteen of the RJ45 Female ports are located on the rear of the unit with four pins of each RJ45 T1 channel switched (paired 1&2 and 4&5).


Cables for interconnection are available from stock.  For more information about Electro Standards’ Network Switches or cables, call 401-943-1164, eslab@ElectroStandards.com, or www.ElectroStandards.com.  All ESL products are available for export.  Government Agencies contact Electro Standards for GSA pricing on COTS (Commercial-Off-The-Shelf) network switches.
