Adaptor

Digital trunk high-impedance adaptor

BNC-HiZ

It   can be used to make the passive Hiz multiplexing for BNC interface digital   trunk lines for the functions such as the E1 line call records and voice   recording. The input impedance is not less than 2 kΩ, and it not influences   communication.

Digital trunk high-impedance adaptor

RJ45-HiZ

It   can be used to make the passive Hiz multiplexing for RJ48 interface digital   trunk lines for the functions such as the E1 line call records and voice   recording. The input impedance is not less than 2 kΩ, and it not influences the   normal communication.

Digital trunk board interface adaptor

BNC-H2×8

It   is used to convert 2 ox horn interfaces to 8 pairs of 75 Ω non-balanced   impedance BNC interfaces. It can be used for the 4 E1 digital trunk voice   processing boards with PCI or used as an interface converter of high-density   digital trunk voice processing board.
