Installation and Operation Manual Chapter 1 Introduction
IPmux-8/16 Ver. 6.00 Overview 1-7
• Total Transmitted Packet per Second (pps) – a previous IPmux-16 Ethernet
module had a limitation on the total transmitted packet per second (pps) rate
(see
Throughput Limitations and System Usage Control). This limitation is not
relevant for the current Ethernet card.
• Larger Ethernet frame size support (see
Throughput Limitations and System
Usage Control).
• Fiber optic Ethernet uplink – two ordering options for the Ethernet uplink
interface are available, in addition to the regular electrical interface:
 Electrical Ethernet uplink
 Fiber optic single-mode Ethernet uplink
 Fiber optic multi-mode Ethernet uplink.

It is possible to determine whether the Channel Service Unit (CSU) Loop Code
(upstream/downstream) is handled locally or transmitted to its parallel
far-end channel via the packet-switched network. The CSU/DSU performs
protective and diagnostic functions for the telecommunications line.

Operation Modes for E1/T1
There are three operation modes for E1/T1:
• Unframed
• Fractional E1/T1
• Fractional E1/T1 with CAS
Multibundling
A bundle is a group of timeslots originating from a specific E1 or T1 channel. Up to
31 bundles per E1 channel and 24 bundles per T1 channel can be defined for
transport over the network. Each bundle can contain 1 to 24/31 timeslots (T1/E1
respectively).
It is recommended to configure up to 85 TDMoIP bundles for optimal agent
operation. Up to 85 TDMoIP bundles can be handled before any degradation in
management access is noticed.
