BayStack 460 Layer 2 switch

The BayStack 460 Layer 2 switch, shown in Figure 12 on page 63, adds power in addition to data communications over standard Category 5 LAN drops for powering the IP Phones. The LAN power system eliminates the need to connect each telephone to an AC power outlet saving in desktop wiring and also allowing centralized UPSs for power backups. Using a Power over LAN unit eliminates the need to use separate power transformers for each IP Phone.

MRV Terminal Server

The Terminal Server, described in Table 8 on page 65, provides the dedicated rlogin service used to establish serial connection between a CS 1000E and various serial devices. The IP-based Terminal Server provides standard serial ports for applications that use a serial port interface. These applications include billing systems that analyze Call Detail Recording (CDR) records, Site Event Buffers (SEB) that track fault conditions, and various legacy applications such as Property Management System (PMS) interface and intercept Computer applications. In addition, serial ports are used to connect maintenance terminals and modems for support staff.
