This attribute indicates the internally (In Mux) connected port. The valid port number depends on the IO slot no., the installed card type and the port type: outside, inside, SP. * The outside ports will be the T1/E1 cards ports. The convention used will be (for DXC): - first two digits will be: (IO slot number+10) for a stand-alone unit, the IO slot will be considered 1. - last one/two digits will be the port number within the card, in odd numbers: port1 = 1 port2 = 3 port3 = 5 etc... Example: port2 of IO slot 11 will be: 213 . * The inside ports will be for example, the HS cards ports. The convention used will be (for DXC): - first two digits will be: (IO slot number+10) for a stand-alone unit, the IO slot will be considered 1. - last one/two digits will be the port number within the card, in even numbers: port1 = 2 port2 = 4 port3 = 6 etc... Example: port2 of IO slot 11 will be: 214 . * noConnection - will be indicated as 10 for DXC and FCD-E1/T1. - will be indicated as 100 for FCD-E1/I and SMODs. * Split TS (same TS is Split to several ports) - 11. * notApplicable- will be indicated as 100 for LRS IMODs. All HS port's timeslots must have the same destination port.
