IC-4BRV 8-channel gateway interface card for ISDN BRI
The IC-4BRV is a PMC standard compatible interface card for the SmartNode 2000 series. It provides 4 ISDN
BRI interfaces and connects through a PCI packet and PCM circuit interface to the SmartNode base unit.
The IC-4BRV supports up to 8 simultaneous voice or fax calls. It is a flexible ISDN networking card designed
to meet the needs of small enterprises that want to connect their ISDN equipment, such as an ISDN PBX, via
multiple BRI interfaces to a multi-service IP network.
The ISDN interfaces can be configured as user or network side interfaces. Its on-board, dedicated micro-con-
troller and DSPs off-load the CPU of the SmartNode 2000 base unit and hence guarantee the conversion of
voice/fax circuits into related IP-packets in real-time with minimal delay and jitter values.
Table 12. Jumper configurations
No jumpers are set. In this configuration, no line power is fed to port. Use this setting for
USR
ports when connected to an ISDN NT.
Normal feeding. Use this setting when the port is configured as
NET and a line-powered termi-
nal is attached.
Inverse feeding. Same function as in normal feeding, except that the polarity is inverted
(required in some countries, Japan, for example).
