SDH E3 or DS3 payload

Overview

The following example, illustrated in Figure 16-9, Channelized 4 × OC-3 port structure using AU3/E3 sub-channels , shows the channelization sequence for an E3 or DS3 payload on a 4 × OC3 Deep Channel card using AU3 sub-channels.

1. Four OC-3 ports are created when you create a channelized 4 × OC3 Deep Channel card.

2. Each port can be channelized into up to three AU3 sub-channel.

3. Each AU3 frame can be channelized into an independent E3 or DS3 data channel.
