NEW PRODUCTS AND NEW WRINKLES FOR
Dial Line REBOOTERS and SWITCHES
Innovative Data and Telephony Products
CPS manufactures out of band (dial-line) products in the following categories:
You will notice that the products may have threads in different categories even
though it may not be the primary objective of that particular product. It is
included because it may serve as the most expedient method of carrying out the
design objective for that product.
As an example, some of the following REBOOTING products utilize a LOCK and KEY
type of security handshake similar to the CPS Challenger
authentication systems. But the Key (a.k.a. hardware token) is also used to select a
port or carry out the rebooting action. The security aspect may not be currently
required, it is free, and it may make an auditor smile someday. Fat chance.
However, secure access, more than just touch-tone passwords, is becoming an
increasingly important consideration for many customers and some of the new
product and new wrinkles are oriented in that direction.
Another trend is toward sharing the phone line with other devices.
Out of band (dial) rebooting may be used only occasionally. Often it is used only
as a backup to rebooting over the network or the Internet, so the economics of
dedicating a phone line to that task may be questionable. Sharing the line
turns out to be a very favorable alternative.

3P-RRC & SP-RRC
Remote Rebooting Products
These Touch-Tone Reboot Controllers (Local or Remote) are more flexible versions of previous products. They can support either an Optional Intelligent AC power strip ($79.00 less discounts) and/or a Reset Button Adapter ($15.00 less discounts), through which the reboot or reset is performed.
The AC Power Strip option provides additional ON/OFF touch tone commands, whereas the Reset Adapter simply connects to the reset button pins of the target PC platform and performs a reset when initiated.
Longer Cable Runs and Line Sharing
All three products perform basically the same functions, but are packaged for large and small requirements.
The single port unit (SP-RRC) has only the Default Port in addition to the TelCo Line Port. To share the line, the AC power strip or the Reset Button Adapter are connected to the default device through a RJ-11 "Y" adapter.
You can play this same "Y" adapter trick on the 3P-RRC (Two Controlled Ports and the Default Port) to control three devices while still sharing the line with the default device.
Remember these are not switching devices. They are simply reset devices for one or more ports. If you are interested in remote switching devices that can also handle the reset devices, see the MRS, the FTS or the 2C on our web site.
They work like this:
Security Key Based Remote Reset
This is a case where the Security Key provides an expedient method to initiate the reset function without requiring the entry of tone commands. It also provides a high level of authentication even though it may not currently be required by the application.
It allows you to quickly change the security codes in all of the units in the field in the event that one of the Keys or an employee turns up missing. This can be done remotely or locally.
First decide what you are trying to accomplish. If you want to use Touch-Tone controls and share a line that has a modem on the default port, you need a product that will answer the line itself and isolate the modem until the Touch-Tone commands can be deciphered. The products that answer the line are the MRS, the FTS, the MP-RRC, the 3P-RRC and the SP-RRC. Key based products do not have this consideration.
If something else answers, such as a fax, voice, answering machine or PBX you can consider the 2C, the RRU, or the K-RRC. They are a little less expensive since they don't have the return ring back circuits.
Next consider if you actually want to switch the call to another remote port or if you just want to reset/reboot equipment on another port. The Reboot/Reset only controllers are a little less expensive, but the Switching controllers can also support the optional Reboot/Reset devices.
The Reboot/Reset only product options are the MP-RRC, the 3P-RRC, the SP-RRC, the RCU and the RRU. The Switching products are the MRS, the FTS, and the 2C.
Next consider if high security is an issue. If yes, select one of the products that is controlled with a KEY. Consult the CHART on the last page for additional help.
It is the latest line up of the rebooting products and remote sharing switches that also have a rebooting function.

Flexie Telephone Switch
This Touch-Tone controlled product allows a caller to select up to three different remote analog ports to connect the call. The password and port selection Touch-Tones can be entered manually or appended to the AT dial string of the calling modem. It is a down-sized version of the Modem Router Switch (MRS).
For additional application flexibility, it can also support the optional Intelligent Power Strip or the Reset Adapter on any port.
It also has automatic fax recognition. So if connected to a fax line (most common "shared line" for small business applications), the call goes immediately to the fax machine if desired. This product can be reviewed at http://www.cpscom.com/gprod/fts.htm.
RS-232 PORT SELECTION
However, where security is an issue, a new 232-PSS PROGRAMMER ($99.00) has been developed to expand the security aspect of the product.
It allows you to quickly call all of the RS-232 PSSs and change the security codes in the event that one of the keys or employees turn up missing. This can be done remotely or locally on the bench. It is also used to program new 232-PSSs and Keys.
This may be a very real consideration in cases where you have a number of maintenance people that may change jobs frequently or if you wish to use another maintenance firm.
One rather interesting application for the 232-PSS didn't involve remote port selection at all. Instead it went the other way using it to share one modem between multiple PCs.
It involved satellite modems aboard ships. Since the satellite modem did not have a standard analog phone port, the only way to share it was through its RS- 232 port.
The 232-PSS provided the RS-232 connections to the modem and the PCs. It also arbitrated the 232 signals so that one PC could not talk while another was using the modem.
Of course, the usual method of sharing phone lines between multiple PCs, or more specifically their modems is with the (TSS) Telephone Line Sharing Switch. It can share up to six phone lines between an unlimited number of PCs with modems.

This product was designed to control maintenance access to remote or local modems by outside vendors. With open modems you may not know who or when new software is loaded on your system. This may result in considerable confusion, viruses as well as outright liability.
With the CAS, the system administrator can assign a one-time password to a remote modem. The scenario is as follows:
This is not restricted to maintenance applications. It can be used to selectively allow access to any network for any reason.
A similar concept can be achieved by using one of the remote AC power controllers and simply calling the modem and powering it on with the instruction to power it off after the next call. If this is of interest, check out the 2C or any of the RRCs previously discussed.
