Function
The 8RS232H card is a RS232 service access card. It can work as a
Data Circuit Terminating Equipment (DCE) or Data Terminal
Equipment (DTE). It provides the following functions:
Provide 8 ways of RS232 service access.
Support concurrent transmission of handshake signals and data
services. You can configure the 8RS232H card to transmit data
services only.
Support configurable bandwidth of 64 kbit/s, 128 kbit/s, and 256
kbit/s.
Support configuring an interface to DCE or DTE mode. The
RC3000-15 automatically chooses the interface mode according to
the cable (provided by Raisecom or made as specified in the
appendix) connecting it and the peer device. By default, the interface
mode is DCE.
Support realtime querying of content of each handshake signal
through the NMS.
Support data collinear function. Namely, among multiple nodes, data
sent by a node can be received by other nodes.
Support configuring data collinear interface group for each RS232H
interface. By default, RS232H interfaces 1–8 are mapped into data
collinear interfaces 1–8 respectively. The rest of data collinear
interfaces 9–16 are idle. Each RS232H interface can be mapped into
up to 16 data collinear interfaces.
Support external loopback on each interface.
Support EMC and overcurrent protection.
