through RS-232, RS-485, and Ethernet interfaces. The SCU manages the Mechanized Loop Test (MLT) feature and controls the activation/deactivation relays. Compliance Table 1 shows the Compliance Codes for the Total Access 1500 SCU. The SCU complies with the requirements covered under UL 1950 and is intended to be installed in Restricted Access Areas only and in equipment with a Type “B” or “E” enclosure. NOTE At this point in the installation, power should not be applied to the Total Access 1500 shelf.
PAGE 3
Craft Port The SCU provides an RS-232 serial asynchronous craft access port. Physical access is attained by connecting a male-ended DB-9 cable to the female DB-9 connector on the SCU front panel. This port can operate at various baud rates and is limited to 8-bit asynchronous data with no parity, one stop bit. Minimal 3-wire functionality (pins 2, 3, and 5) is also accommodated. This port operates as a DCE; pin assignments are detailed in Table 3. 3.

Telnet The SCU will support four concurrent Telnet sessions. Telnet is supported via the Ethernet interface. To use Telnet to communicate with the SCU, use the following steps: 1. Set the proper IP Address for the connection method of choice via the provisioning menu. For this procedure, refer to the following page of this practice. 2. Connect to the Ethernet Interface on the backplane of the Total Access 1500 shelf. NOTE The IP Address, Subnet Mask and Gateway are in the form XXX.XXX.XXX.

the user to view all provisioning settings, alarms, and statistics. An account with Test privileges will also allow the account to perform tests. Figure 2 illustrates the menu structure of the SCU. Submenus are elements that move the user down to the next menu level. Menu items are elements which allow the user to make changes to the current SCU settings. There are two different types of menu items: read-only and read-write.
