Three new AC powered models have been added to the TSS (Telephone Line Sharing Switch) family; the 1x4-M, the 1x8-M and the 2x4-M. The 1x4-M and 1x8-M allow one telephone line to be shared among four or eight users, respectively, and the 2x4-M allows two telephone lines to shared among four users In the event that you are not familiar with the TSS family of line sharing switches, they are primarily used for outbound access to allow a number of modems to share a lesser number of telephone lines. They also address inbound calls, but not in a shared mode. Using the TSS, any modem or fax or voice set for that matter, can bid for any available line. Line utilization really increases when it's shared between multiple callers. It's great for shared Internet access. Although this is not an "IP address sharing unit", it can be used with them to provide access to lines that may be available. Various models are available that can handle from 1-6 telephone lines with up to 64 outbound modem ports (see TSS Expansion Modules). Inbound calls are designated to specific ports, depending on the model.
TSS Customer Comments "The TSSs fit our real estate application like a glove. The agents are out most of the time, but when they come in, they need the lines." "Our 200 store installation was completed without a hitch. The TSSs and Challengers provided a straight forward installation."
Newer modems try to error correct the call waiting tone making it invisible to the user. The Call Waiting products connect to the phone line like an answering machine and filter the call waiting tone from the overlapping modem signals. They alert the user, through a beeping sound and a flashing LED that a call is waiting. The user may accept the call or ignore it. A larger software controlled model can also recognize Caller ID. It provides a "screen pop" to the identity of the caller. The three call waiting products can be further reviewed at http://www.cpscom.com/cwp.htm.
The ATTACHED CHART summarizes the TSS family of products, Call Waiting Switches, as well as others.
They are normally used for remote maintenance applications, to select various servers or to selectively control AC power remotely. They also function as outbound Sharing Switches when outbound calls are placed. If you would like further information on any of the products, please call: 1-800-888-0051 or visit our web site.
Simply by placing one Challenger Security Key ( CPS's family of Dial Security Products) on each line or at specific work groups, any of the systems in that group can access a corporate system that is secured with corresponding Challenger Lock. Other outbound calls to non-secure sites, such as to the Internet, pass through transparently. See diagram. Inbound calls can be handled in a similar manner. By placing a Challenger Lock on a server or a work group line, only authorized calls with a Security key connected to the callers modem will be able to access the secured server. This is great for remote maintenance applications on shared telephone lines. The server or other monitoring equipment may also place outbound "alarm calls". This can be a very flexible system depending on where and which type of Challenger Locks and Keys are used. The Inbound Sharing Switches already have various built in security measures so the Lock may not be necessary, only the Keys on the callers modem. Some also recognized touch-tone passwords and Caller ID. Click here to review the Challenger Dial Security Concept and products.
