Private Networking Over Internet Protocol
Strata Net CTX multi-system networking can be implemented over an IP network using Strata
CTX systems with BIPU-Q1A IP interface PCBs. The BIPU-Q1A requires CTX Release 2.1
software. This feature offers the same connection service as ISDN dedicated lines with QSIG
protocol on the public network. QSIG over IP, like any other IP device (i.e., Cisco routers, etc.)
does support reliable passage of modemized data signals, such as modem signal and G3 fax.
BIPU-Q1A - Strata Net QSIG over IP Interface Unit
Circuits per PCB:
eight or 16 circuits
Interfaces with:
Strata Net over IP Networking
Older Version(s):
None
The BIPU-Q1A can be configured for up to 16 channels in system programming. The BIPU-Q1A
supports the same functions of call control as the dedicated ISDN QSIG interface and the two
interface types can be mixed in on a Strata Net network. However, the BIPU-Q1A only interfaces
with the BIPU-Q1A, not with the BPTU or RPTU interfaces and vice versa.
For bandwidth requirements, refer to the section “Strata Net QSIG Over IP and IPT Bandwidth
Requirements” on page 9-41.
Refer to “Dos and Don’ts for Setting Up the System” on page 9-2 if you are planning to mix
analog and IP QSIG circuit cards in the same Strata CTX system.
An example of Strata Net QSIG over IP networking is shown below.
