13 Cross Connect (XC) Registers
(continued)
DS1/E1 crosspoint connectivity is determined by a set of source identifiers (SOURCE_IDs), one for each channel
leaving the crosspoint switch. A DS1/E1 SOURCE_ID is therefore defined as follows:
The SOURCE_BLOCK is defined as:
The CHANNEL_ID typically ranges from 1 to 28 (29 for external). Values 0, 30, and 31 (and usually 29 as well) are
unused. The above definition is valid for XC_PDATA[1—29], XC_RP_RDATA[1—28], XC_MDS1DATA[1—29]
