136 Strata CIX General Description 12/07
Private Networking Over Internet Protocol
System Availability: All systems
Strata Net CIX multi-system networking can be implemented over an IP network using Strata CIX
systems with MIPU / LIPU / GIPH IP interface circuit cards. This feature offers the same
connection service as ISDN dedicated lines with the Strata Net protocol on the public network.
Strata Net IP, does not support modemized data signals, such as modem signal and G3 fax because
these signals require very low jitter and low delay on the networks.
The MIPU16 / LIPU can be configured for up to 16 channels in system programming. The
MIPU24 can be configured to 24 channels. Adding the LIPS to the LIPU enables you to configure
the system to 32 channels. The GIPH can be configured to 8 channels. CIX Strata Net private
networking over IP can support up to 128 separate nodes.
For bandwidth requirements, refer to the section “Strata Net IP and IPT Bandwidth Requirements”
on page 175.
Refer to “Analog CO Line Interface Compatibility” on page 133 if you are planning to mix analog
and Strata Net IP circuit cards in the same Strata system.
MIPU / LIPU / GIPH interface parameters include:
• 100Base-TX: Automatic recognition and switch
• Transmission: TCP/IP, UDP/IP
• Protocol: Based on IP QSIG (ECMA-336), NAT compatible
• Protocol: RTP/RTCP for voice transport
• Voice coding: G.711, G.729A, selectable
• Priority process: Diffserv/IEEE802.1p
An example of Strata Net IP networking is shown below.
