5-2 Overview
Guidelines
Certain guidelines/assumptions for configuring IPmux-1 working opposite
IPmux-4 that are relevant to this application are explained below.
IP Configuration
• The IP network can consist of either switches or routers. The minimum
requirement is 10M full duplex. Hubs or any half-duplex environments should
not be used.
• Each IPmux should be given an IP Address and a Default Gateway (if a routed
network is used).
E1/T1 Configuration
• TDM traffic will be sent between the central IPmux-4 and the two remote
IPmux-1 units at Station A and Station B over the IP network.
• The TDM traffic can either be generated by a BER tester connected to the
IPmux units or by a PABX. If a BER tester is connected to IPmux-4, a physical
loop can be inserted in the remote IPmux-1 E1 port to avoid using more BER
testers.
• The TDM equipment connected to the central IPmux-4 should be the clock
source for the whole application (i.e. it will operate in internal mode). The two
other TDM devices connected to IPmux-1 receive the clock from the Tx path
of the IPmux-1 units.
• Set the TDM device’s E1 parameters in accordance with the E1 parameters of
the IPmux units connected to them. For details, see Table 5-1and Table 5-2,
and the E1/T1 Configuration on the following pages.
• On the IPmux-4, only E1 port 2 will be used to connect to the remote
IPmux-1 units.
Creating Bundles and Connections
• After IP addresses and E1 parameters have been configured, create bundles on
each IPmux, followed by connections between the bundles.
• A bundle is a group of timeslots, encapsulated in UDP over IP over ETH
frames, which is sent over the IP network between the IPmux units. A bundle
can include between 1 and 31 timeslots for E1, and 1 to 24 for T1.
IPmux-1 can only be configured for 1 bundle. IPmux-4 can be configured to
have up to 31x4=124 bundles for E1 or 4x24=96 for T1. Each configured
bundle is given a Bundle Number that indicates to which E1 channel it
belongs, according to Table 5-1.
