Section 6 – Configuration Using ISiCL
Intraplex CrossConnect systems and servers can be controlled using the Intraplex Simple Command
Language (ISiCL, pronounced “icicle”). ISiCL works in a command–response mode, where the DCS
only generates messages in response to ISiCL commands from an external controller.
ISiCL commands can be entered manually, you type commands on the controller’s keyboard and view
the responses on the terminal display, or a network management system can enter the commands
automatically.
6.1 Hardware and Protocol
6.1.1
Remote Port
Each CM-95 module has two remote ports-one for connection to the PC, the other for daisy-chaining
to CM-5s or to other Intraplex network access products. CrossConnect Servers with terminal
multiplexing has two remote ports, while Access Servers with drop/insert multiplexing have only one
remote port. CrossConnect Server remote ports are RS-232/485 compatible, asynchronous, serial
interfaces which operate at a fixed baud rate of 9.6 bps.
The DCS is preset to 9600 baud, 7-bit word, no parity, and cannot be changed. For communications
over a network, all CM-5 modules should be set to match this DCS protocol.
The
T1 Access Server Installation and Operation Manual
gives information on setting the remote port
baud rate and parity. Section 3.5.3 –
Remote Port Wiring (Optional)
in this manual gives remote port
pin assignments.
6.1.2
Handshaking
ISiCL does not support hardware or software flow control or “handshaking,” which is not an issue
when entering ISiCL commands manually from a terminal or PC keyboard. However, if you plan to
download setup information or poll for status information using a PC or any other type of automated
controller, be aware that flow control must be handled by the controller itself. Generally, controller
software must be designed to wait until it has received a response to the last command sent to a
given Intraplex Series multiplexer before issuing another command to the same multiplexer.
6.1.3
Data Circuits
For local operation, connect a controller directly to the remote port on the Intraplex CrossConnect
server or system using an RS-232 cable. Or, using modems, establish a remote connection over a
dial-up voice circuit.
Intraplex CrossConnect servers or systems can also be connected to a controller over a public
switched network, which can be DDS, X.25, or any type of data network capable of providing
asynchronous RS-232 interfaces for the Intraplex remote ports. ISiCL commands issued over switched
network circuits may include the network address of the “target” multiplexer to facilitate record
keeping and network management.
6.2 ISiCL Command Line Format
An ISiCL command line contains four fields, separated by colons. Each command line must be
terminated by a semicolon and carriage return:
<address>:<subaddress>:<command>:<parameter=value>;
For example, to set the primary clock to “external” in a DCS whose shelf address is 13, you would
type
