Clock source type. Includes the line clock source, BITS clock source, and local surge source. If it is line clock source of a CES port, the clock source type may be CES line or CES SRTS clock source. If it is BITS clock source, the clock source type may be 2 MHZ or EL clock source of BITS0, or 2 MHZ or EL clock source of BITS1. If the value is 1, it indicates that a clock source is not configured. Options: 1.none(1) - indicates that clock source not configured 2.sysLine(2) - indicates that line clock source that needs to specify frame/slot/port 3.cesLine(3) - indicates that line_clk of a CES clock source 4.cesSrts(4) - indicates that srts_clk of a CES clock source 5.e1Bits0(5) - indicates that EL type of a BITS0 clock source 6.e1Bits1(6) - indicates that EL type of a BITS1 clock source 7.f2mhzBits0(7) - indicates that 2MHZ type of a BITS0 clock source 8.f2mhzBits1(8) - indicates that 2MHZ type of a BITS1 clock source 9.msuSdh(9) - indicates that sdh_clk of an MSU clock source 10.msuTdm(10) - indicates that tdm_clk of an MSU clock source 11.localSurge(11) - indicates that local surge clock 12.xpm8k(12) - indicates that xpm-8k type of a xpm-8k clock source 13.gPON(13) - indicates that 2MHZ type of a clock source at H601GP1A board 14.pkt1588(14) - indicates that frequency synchronization from 1588 15.pw(15) - indicates that Pseudo-Wire clock source 16.copa(16) - indicates that EL clock source of H601COPA board 17.adaptClock(17) - indicates that clock adapt from CESoP 18.aCMClock(18) - indicates that ACM clock 19.t1Bits0(19) - indicates that TL type of a BITS0 clock source 20.t1Bits1(20) - indicates that TL type of a BITS1 clock source 21.system(21) - indicates that system clock source 22.acr1588(22) - indicates that 1588ACR clock source 23.syncEth(23) - indicates that syncEth clock source 24.pvx2m(24) - indicates that PVX-2M clock source
