1-6 Functional Description

Front Panel

The control port and indicator LEDs are located on the front panel of IPmux-16.

For further details see Chapter 2.

Rear Panel

Fuses, power supplies, the dry contact connector, and interface connectors are

located on the rear panel of IPmux-16. For further details see Chapter 2.

1.3 Functional Description

IPmux-16 modules support E1 or T1 TDM interfaces. The E1 and T1 modules have

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

predefined destination bundle (see the following figure). IPmux-16 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-16 local terminal,

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

System.
