Both types adopt HD100PIN connectors with pin spacing of 1.27 mm,and each cable includes 16 channels of E1 or T1 signals.l The 75-ohm E1 trunk cable is 32-core coaxial cable with the impedance of 75 ohms, andthe 120-ohm E1/100-ohm T1 trunk cable uses 32 twisted pair cables with the impedanceof 120 ohms and 100 ohms respectively.l E1 interface, the cable type can be the 120 ohm twisted pair or 75 ohm coaxial cable.l T1 interface, it can be the 120 ohm coaxial cable.l Cables with different resistance features correspond to different grounding modes. Forexample, the E1 coaxial cable with 75 ohm resistance corresponds to non-balancedgrounding, and the twisted pair with 120 ohm resistance corresponds to balancedgrounding. 16. l FEp The external network cables are used to connect the UAP8100 with externalnetwork devices, and the external network ports in the UAP8100 are provided bythe corresponding back interface boards.l GE: Gigabit Ethernet. 17. l External clock cables include 2 Mbit/s external clock cable. The 2Mbit/s clock cable is BITSclock cable, which has SMB female connectors. It is used to access the synchronous clocksignals provided by external BITS.l Internal clock cables include clock distribution cable and 8-kHz clock cable. One end of thecable has a DB26PIN plastic connector and the other end has six UL2464-28AWG-100cables with RJ45 connectors, which correspond to three MGW frames. 18. l UAP8100 has open and standard protocol interfaces and supports a number of signalingand protocols to interwork with many devices.
