Network Communications Module

DESCRIPTION

The Network Communications Module (NCM) is an Asynchronous Data Module designed for use in
RFL IMUX 2000 T1 and E1 multiplexers. It provides one DCE Half/Full-Duplex channel between an
unlimited number of locations using a single 64 kbps DS0 time slot. The NCM provides a fast and
reliable NMS communication path between nodes of a T1 or E1 network, and can also be used for
party-line applications such as DNP and Modbus networking.

The NCM is remote-controllable when installed in an RFL remote controllable shelf. The following
module parameters can be configured remotely via NMS or locally via DIP switches. A DIP switch
setting selects whether the card is in remote or local mode.

INSTALLATION

Before the RFL NCM module can be placed in service, it must be installed in a multiplexer shelf.
Installation involves determining the module slot in the Main Shelf or Expansion Shelf where the
module will be installed, inserting a Module Adapter into the rear of the shelf behind the module slot,
connecting all signal and power wiring to the Module Adapter, checking the settings of all switches,
and inserting the module into the front of the shelf.

NOTES

Power supply and time slot considerations may affect the installation of this module into an
existing multiplexer shelf. Refer to the multiplexer manual for more information.

The following instructions are provided for installing an RFL NCM module into an existing system. If
the module was included as part of a system, installation was done at the factory. Otherwise, proceed
as follows:

1. Carefully inspect the module for any visible signs of shipping damage. If you suspect damage
to the module, immediately call RFL Customer Service at the number listed at the bottom of
this page.

2. Determine the module slot in the Main Shelf or Expansion Shelf where the module will be
installed.

The RFL NCM module occupies one module slot in the Main Shelf or Expansion
Shelf.

3. Determine which module adapter will be used to make connections to the RFL NCM module.

Each module in the IMUX 2000 multiplexer requires a Module Adapter. The
module adapter provides the appropriate connector for the desired interface.
There are three Module Adapters that are compatible with the RFL NCM:

Module Part Number Interface Type Connector Figure

The MA-402I module adapter is shown in Figure 1. This module is a two-port RS­232 I/O which has two 9-pin D-subminiature (DC-9) connectors on its rear panel.
Each of these 9-pin connectors is wired in a standard RS-232 configuration as
shown in the table at the bottom of the figure. Each connector is labeled to show
the corresponding port on the NCM module.

The MA-485 module adapter shown in Figure 2 supports both 2-wire and 4-wire
RS-485 applications. The 2-wire mode supports only half-duplex, and the 4-wire
mode supports both half and full duplex. The MA-485 is typically used for party­line applications such as DNP and Modbus networking, or simple point-to-point
applications. This module has one 6-position removable terminal block on its rear
panel, which is wired in accordance with the table in Figure 2.

The MA-490 module adapter shown in Figure 3 is an RS-232/Telnet I/O module
adapter used for systems that have an RS-232 port which needs Telnet link
capability. This module has two RS-232 ports using DB9 connectors and one
Ethernet port using an RJ-45 jack on its rear panel. One of the RS-232 ports is the
Craft port and the other is the Data port. The Craft port is used to set up TCP/IP
parameters, and the Data port is used for communications. Refer to the tables in
Figure 3 for wiring information.

Make sure the module adapter you are installing is correct for the desired
application. Make sure the programmable jumpers on these modules are set to the
desired configuration, as applicable.

4. Insert the Module Adapter into the rear of the shelf directly behind the module slot where the
RFL NCM module will be installed. Secure the module with the screws provided.

5. Connect the Module Adapter to the user equipment using the connector pin assignments
detailed in Figures 1, 2, or 3 as applicable.

6. Refer to Figures 4 & 5, and Table 1 for the location of DIP switches on the NCM module.

7. Set the module address using DIP switches SW1-1 through SW1-6 for the desired remote
address (SCB address).

For remote access, each channel module in the IMUX 2000 must have a distinct
module address. Valid addresses are the numbers “1” to “36”. In most
installations the address will be set to the number of the slot the module is
occupying. Table 3 shows the switch settings for the module address. (Consult
your multiplexer manual for details on using the remote access and configuration
features of the system.)

8. In E1 systems, set DIP switch SW2-8 to enable or disable CAS (channel associated signaling).
In T1 systems, this switch setting is ignored.

Place SW2-8 in the UP position to disable CAS.
Place SW2-8 in the DOWN position to enable CAS.

9. Select an unused time slot for the NCM using DIP switches SW2-1 through SW2-5. The NCM
uses one 64 Kbps digital time slot within the multiplexer’s aggregate rate. Set the time slot
using direct binary coding as shown in Table 4. Refer to the multiplexer manual for guidelines
on time slot selection.

Note that selecting an invalid time slot will disable the module. In T1 systems, only time slots 1
through 24 are allowed.

In E1 systems, time slots 1 through 31 are allowed, however, time slot 0 is reserved and cannot

be used. Time slot 16 is also reserved and cannot be used if CAS is enabled in E1.

10. Select Bus direction by using DIP switches SW2-6 and SW2-7.

Place SW2-6 in the DOWN position to transmit in the A direction and receive
from the B direction. Place SW2-6 in the UP position to disable transmit in the A
direction and receive from the B direction.

Place SW2-7 in the DOWN position to transmit in the B direction and receive from
the A direction. Place SW2-7 in the UP position to disable transmit in the B
direction and receive from the A direction.

11. Switches SW3, SW4 and SW5 are only used when the NCM module is in the NMS application
mode. In all other application modes these switch settings are ignored. Set Rotary Switches
SW3, SW4, and SW5 to the local CM address. SW3 sets the hundreds position, SW4 sets the
tens position, and SW5 sets the units position. The NCM supports CM addresses from 001 to

999. The “local CM address” must be set to the same address as the local Common Module
(CM3B, CM3C, CM3R, CM6B, or CM4).

12. Set DIP switches SW6-1, -2, and -3 to set the baud rate in accordance with Table 1. If the
system application mode is NMS, the baud rate must be set to the same baud rate as the local
common module. Otherwise, any baud rate can be used.

13. Set DIP switches SW6-4, -5, and -6 to set the parity in accordance with Table 1. If the system
application mode is NMS, the parity must be set to the same parity as the local common
module. Otherwise, any parity can be used.

14. Set DIP switches SW6-7 and SW6-8 to set the word length (number of bits per character) in
accordance with Table 1. If the system application mode is NMS, the word length must be set
to the same word length as the local common module. Otherwise, any word length can be used.

NOTE

In any Application Mode, the Baud Rate, Parity and Word Length settings of the NCM must
match at all nodes in the network. Additionally, In the NMS application mode, the Baud Rate,
Parity and Word Length settings of the NCM and CM must match at all nodes in the network.

15. Switches SW7-1 and SW7-2 are only used when the NCM module is in the NMS application
mode. In all other application modes these switch settings are ignored. Use DIP switches SW7­1 and SW7-2 to set the CM address Pass Setting in accordance with Table 1. Typically, if all
the nodes in a T1/E1 network have an NCM as shown in Figure 6, the address Pass Setting will
be set to only pass messages with addresses equal to the local CM address of the NCM. This
feature prevents the local node from responding to queries sent to remote nodes.

Place SW7-1 in the DOWN position
Place SW7-2 in the UP position

In this example, all inter-node communication is done via the NCM path and FDL (Facility
Data Link) is not used.

15. (continued).
If some of the nodes in a T1/E1 network have an NCM, and others do not as shown in Figure 7,

the address Pass Setting will be set differently at some of the nodes. In Figure 7, nodes 1, 2 and
3 have NCM modules, and nodes 4 and 5 do not have NCM modules. This network requires
that at nodes 1 and 2, SW7 is set as follows:

Place SW7-1 in the DOWN position
Place SW7-2 in the UP position

And at node 3, SW7 is set as follows:

Place SW7-1 in the UP position
Place SW7-2 in the DOWN position

Additionally all 5 nodes must have the CM setting UNIV = ON to enable the FDL path. This
allows a user to “transparently” communicate to all nodes regardless of which node the PC is
connected to. If the PC is connected to node 1, 2 or 3, a user can “talk to” nodes 1, 2 or 3 via
the NCM path, and “talk to” nodes 4 and 5 over the FDL path. If the PC is connected to nodes
4 or 5, communication to all nodes is over FDL.
