If “Table” is selected, the individual table values will is prompted for. See Figure 47 on page 285 and Figure 48 on page 286. After each value is displayed, enter <CR> to do the following:

•accept the current value

•enter just the AB bits (which will be copied to the CD bits)

•enter a complete ABCD bit pattern

•in the case of optional states, a ‘N’ or ‘n’ can be entered to indicate that the state is not needed

Note that in D4 Framing for E1, there are no CD bits, so they will be ignored.

The user is prompted for ABCD bit values for the following states when the table mode is selected.

Send and Receive refer to the LEI sending ABCD bits to the CPE (Customer Provided Equipment) or receiving ABCD bits from the CPE.

Incoming and Outgoing refer to E1 digital link from the CPE point of view. Incoming is thus an external call arriving over the digital link and accepted by the CPE. Outgoing is a call originated by the CPE over the digital link.

Configuring the A/B Bit Signaling table is illustrated in Figure 47 and
