 H1016 High-resistance Access Box Access Instructions: With a high-impedance bridging method, there is no high impedance on the original line, which needs to be bridged on the signaling link through a high-impedance box, which does not affect the existing network.
The high-resistance box has a front and a back, with a loop interface on the front and a jumper interface on the back.
The front of the high-resistance box is composed of RJ48 (ie, the crystal head effective line sequence is 1245) mouth and the BNC-Q9 female head. Each RJ48 mouth is connected with a pair of BNC-Q9 female heads on the left and right sides. Each two RJ48 ports are each a loop group, and the loop group collocation is fixed. (All Ctrl/Net ports on the high-impedance box are not valid in the high-resistance jumper). Each ring group and the back of the high-resistance box have a one-to-one correspondence across the interfaces. The corresponding relationship is shown in the following table: Explanation: Twisted pair access 2 pairs E1 The signaling link on PBX1 is connected via line A to RJ48 port numbered 2 on the front of the high-impedance box. The RJ48 port ring numbered 1 is formed by the loop of the same group and is connected to PBX2 through line B. Lines do not produce shadows. Similarly, the signaling link on PBX1 is connected through line E to the RJ48 port with the front number 10 of the high-impedance box, and the RJ48 port ring with the number 9 in the same group forms the ring, and is connected with PBX2 through the line F. No effect on the original line. Line C will access the signaling link on loop group 1 and loop group 5, and access the corresponding signaling link to the MEDOU acquisition device through C-1 and C-2, respectively, due to the loop combination The interface directly connected to the internal circuit has a high impedance. Therefore, if the MEDOU acquisition device is connected across the uplink, it will not affect the original line. The line sequence requirements for Line A, Line B and Line C are shown in Table 2: Table 2: 1.1 Twisted Pair Access MEDOU Device Architecture Diagram 1.2 Coaxial access to the MEDOU device architecture Explanation: BNC coaxial access to 2 pairs of E1: The signaling link on PBX1 is transmitted and received through the coaxial line AR on the line, and the BNC females on both sides of the RJ48 port with the AT access number 2 pass through the BNC females on both sides of the RJ48 port corresponding to the loop group numbered 1. Coaxial BT, BR access PBX2 to enable signaling links. Similarly, the second signaling links of PBX1 and PBX2 are connected through coaxial lines E-R, E-T and F-R, and F-T. Line C will access the signaling link on loop group 1 and loop group 5, and access the corresponding signaling link to the MEDOU acquisition device through C-1 and C-2, respectively, due to the loop combination The interface directly connected to the internal circuit has a high impedance. Therefore, if the MEDOU acquisition device is connected across the uplink, it will not affect the original line. Line C's practice is shown in Table 2: Table 2: |
