6.10 Installing Transmission System Cable
ZXG10 iBSC transmission system cables connect the external E1, T1, Ethernet (FE
electric port, GE optical port, and GE electric port), and STM-1 optical fiber.
6.10.1 Installing E1 Trunk Cables
Context
ZXG10 iBSC system provides two types of E1 cables: 75 Ω micro coaxial trunk cable and
120 Ω balanced trunk cable. The configuration is flexible according to the requirement.
When connected with external equipment, such as transmission equipment or cable
distribution frame, the shielding layer grounding of the connection cable can adopt
dual-end grounding mode. That is, the transmitting end must be reliably grounded. The
receiving end is grounded and at the same time, it reserves the possibility to disconnect
the grounding.
There are two kinds of E1 trunk cables.
1.
75Ω E1 trunk cable
It implements 75 Ω non-balanced transmission connection of external 2M interface at
interface A, Abis, and Gb interface.
