The SMT can be locally (within 50 feet) or remotely connected to the
XC1000. If the SMT is installed more than 50 feet from the XC1000, a
modem must be installed at each end of the connection. A null-modem
cable must be used to connect the modem to the XC1000.
The SMT connects to the CPU through the monitor card. This configura-
tion permits troubleshooting the system even if the CPU has failed; alarms
reported by the monitor card can be viewed without a functioning CPU.
The SMT is connected to the distribution board at J50, using a male-to-
male DB25 cable. Pins 1 and 2 on JP2 must be strapped together and the
pins on JP1 must be left open.
In addition to the primary SMT port (J50), serial ports J43, J44, and J46
can be configured for secondary SMT connections for XC1000s using
software releases at Release1.5X and newer. The primary SMT port is a
data-circuit-terminating-equipment (DCE) connector. Because J43, J44,
and J46 are data-terminal-equipment (DTE) connectors, a null-modem
adapter must be used with the connectors. Any of these connectors can be
used, but the XC1000 can only support one primary SMT and two second-
ary SMTs.
If the monitor card fails or must be removed, the SMT can be connected
directly to the CPU using the connector at J45. A null-modem cable or
adapter must be used.
Currently, Octel supports the Fujitsu DL1200 and the Okidata Microline
320 (ML320) printers. Other printers can be used with the proper adapta-
tions. For other printer use, contact the manufacturer’s representative. The
printer connects directly to the SMT. Refer to section 3.10 for the location
of the SMT connectors on the distribution board and for instructions about
installing the printer.
10.9 CALL FLOW
The normal call flow between the switch and XC1000, when the called
party is not available and the caller is forwarded to XC1000, is depicted in
the following example. In this example, the XC1000 is integrated with a
switch through a Simplified Message Desk Interface (SMDI) data link.
Figure 10-18 shows a diagram of the call flow.
