ACCESS IDENTIFIER
Summary:
Circuits displayed in the Craft Interface are identified by the Access Identifier (AID).
Figure 106-1 shows 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
106-1 for DS1 signal routing details. See Table 106-2 for DS2 signal routing details. See Figure
106-2 for chassis slot numbering.
