Engineering Information TABLE 12-2 SX-200@ DIGITAL PABX LOCAL SWiTCHlNG LOSS PLAN ATO * * The AT0 trunk cannot be locally switched. The AT0 trunk can be implemented with an analog CO trunk interface, but it does not have the 2 dB pad required to meet part of the loss plan for local switching. 412.96 All analog interfaces may be represented by the block diagram Figure 12-6 when they are locally switched. Confereneing Loss Plan 12.17 Any SX-2QO@ DIGITAL PABX will have at least one 18 port...
