ACCESS IDENTIFIER

Summary: Circuits displayed in the Craft Interface are identified by the Access Identifier (AID). Figure 106-1shows an example of a circuit with descriptions of each part of the AID. The DS3 signal is demultiplexed by the DS3 MUX into 28 DS1 signals and seven DS2 signals. See Table 106-1for DS1 signal routing details. See Table 106-2for DS2 signal routing details. See Figure 106-2for chassis slot numbering.
