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 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.

o	TX/RX Time Slot	1-31
o	TX Bus Direction	TX-A(RX-B) / TX-B(RX-A)
o	Service enable/disable	On/Off
o	Equipment Loopback	On/Off
o	Payload Loopback	On/Off
o	Block timeslot 16 for CAS in E1 operation	On/Off
o	Port 2	On/Off
o	Rogue Control	On/Off
o	CM Address	Any, Greater Than, Less Than
o	Baud Rate	2400, 4800, 9600, 19.2k, 38.4k
o	Parity	None, Odd, Even, Mark, Space
o	Word Length	7 or 8 data bits
o	Application Modes	Broadcast, NMS, Master, D&I slave, End slave
o	Remote Operation	On/Off
