1 • General Information
Description
The IC-4FXS interface card provides four FXS ports, together allowing up to 4 analog voice channels to work
in parallel.
Each ports provides the following the following:
•
-48 VDC to the connected terminal
•
Ring voltage to the connected terminal (normally 96 VAC at 25 Hz)
•
On-hook transmission
•
Caller identification (CLIP)
•
Metering pulses
•
Recognize dialed digits
The FXS ports must be connected to FXO ports.
Note
When using the IC-4FXS, an internal line power module must be
installed (see chapter 8,
“Line power module installation”
on
page 114). This line power module provides the loop voltage (-48
VDC) and the input to the ring voltage generator.
IC-4BRV-8V 8-channel gateway interface card for ISDN BRI
The IC-4BRV-8V 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-8V 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. In contrast with the IC-4BRV, all
ports can be configured for network or user-side operation. Its on-board, dedicated micro-controller 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.
