Chapter 1 Introduction IPmux-4 Installation and Operation Manual

1-6 Functional Description

1.3 Functional Description

IPmux-4 modules support E1 or T1 TDM interfaces. The E1 and T1 modules have

either one or four ports. Each bundle (group of timeslots) can be transmitted to a

predefined destination bundle (see the following figure). IPmux-4 supports ICMP

(ping), and generates ARP in case of unknown next hop MAC addresses, answers

ARP requests, and supports 802.3 Ethernet format.

Configuration and management are provided via the IPmux-4 local terminal,

Telnet application or SNMP such as RADview, RAD’s Network Management

System.

Figure 1-5. Grooming of Timeslots from Remote Sites into a

Single E1/T1 Port at Central Site

Bundles composed of several timeslots (E1: 1-31, T1: 1-24) can be defined. Each

bundle can be connected to a different destination bundle anywhere on the

network.

Up to 124 sub-E1 or 96 sub-T1 remote bundles can be attached to one central

IPmux-4. Multibundling enables concentrating many remote sites with few

timeslots to the same TDM channel at the central site. A mesh topology

application, in which the bundles at each site are defined to connect to several

sites, is also supported.
