— CONFIGURATION NOTES —

• TAPS units must

be configured in pairs. In each

pair, one unit must be configured as a MASTER

and one as a SLAVE.

• Each pair of TAPS units must

be configured for

the same mode, NORMAL or TRANSPARENT

• A pair of TAPS units configured as NORMAL

may not

be placed in the same circuit with a pair

configured as TRANSPARENT.

• It is allowed (as the diagram shows) to have two

pairs of TAPS units on the same circuit if they are

configured for NORMAL mode.

• Take note of the setting for switches S2-7 and S2-

8. These switches determine the CONFIGURA-

TION SOURCE for the 1557 card. Switch

options for Configuration Source are shown on

the front page of this document. The four choices

are explained in the 1557 Users Manual.

• A 1559 APS Manager connected to a 1557 con-

figured as a MASTER unit can monitor and do

maintenance functions on both the master unit

and its corresponding slave unit.

• A 1559 APS Manager connected to a 1557 con-

figured as a SLAVE unit can monitor only the

performance data for the slave unit. No mainte-

nance functions are available through the slave

unit.
