RFL NCM
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 als

SPECIFICATIONS As of the date this Instruction Data Sheet was published, the following specifications apply to the RFL NCM Module. Because all of RFL products undergo constant improvement and refinement, these specifications are subject to change without notice. Live Insertion/Extraction: The NCM Module is capable of live insertion and extraction into the IMUX 2000 shelf without interruption to the DS1 or any other DS0. Asynchronous Data Interface: Full duplex or half duplex, one

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

The MA-402I module adapter is shown in Figure 1. This module is a two-port RS- 232 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-

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,

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 set

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
