Black Box Explains...Multi-user ServSwitch products vs. multipoint access ServSwitch products.
A multi-user ServSwitch, such as the Matrix ServSwitch, enables two or more users to access different servers at the same time. So, for instance, one user can access “Server A”... more/see it nowwhile another user accesses “Server B.” This is considered a “true two-channel” architecture because two users have independent access to CPUs. It should be pointed out that multiple users cannot access the same server at the same time.
A multipoint access ServSwitch, such as the ServSwitch Duo, provides two access points for control stations but requires that both users view the same server at the same time. So, if one user is accessing “Server A” on his screen, the other user is also seeing “Server A” on his screen. If the second user switches to “Server B,“ the first user will also switch to “Server B.” Only one of these users is actually in control. The user in control stays in control until his workstation is inactive for a period of time (selectable). Then the other station can take control.
A multipoint access ServSwitch is useful when simultaneous, independent access is not required—just the ability to access CPUs from more than one place.

Black Box Explains...Modem eliminators.
Understanding the process of elimination.
If your office environment has sync equipment, and if that equipment is also used for local data communications, you should consider replacing those modems with cost-effective... more/see it nowand versatile modem eliminators.
What does a modem eliminator do?
One modem eliminator can connect a local terminal and computer port in lieu of the pair of modems that they would normally connect to. Plus, a modem eliminator enables DCE-to-DTE data and control-signal connections that are not easily achieved by standard cables or connectors in a sync environment.
Basically, a modem eliminator simulates a sync data link. It does this two ways. First, it provides clocking, which is mandatory for sync devices to communicate. Second, it provides the handshaking that DCEs do.
Why should you use a modem eliminator?
One—if you have two sync DTEs in the same room or close to each other, you will need a modem eliminator.
Two—if you have a network with routers, you just found the perfect equipment tester.
A modem eliminator can enable in-house bench testing of routers or existing equipment. There’s no need to place routers all over your network only to find out they don’t work once you test the LAN. A modem eliminator tells you what equipment passes your tests before you install.
Three—a modem eliminator makes good economic sense. One does the job of two modems—and it does the job better. You get a high return on your investment. collapse
