Connecting To T1/E1 Ports; Connecting To The Advanced Clocking Module - Juniper BX7000 Hardware Manual

CHAPTER 5: Connecting the Gateway

Connecting to T1/E1 Ports

Connecting to the Advanced Clocking Module

36 Cabling the Gateway to Management and Alarm Devices
The gateway has 16 T1/E1 ports. These ports are connected to a switch or a router in the network.
Each T1/E1 port has an RJ-45 receptacle. Use the RJ-45-to-RJ-45 interface cable to connect the
port to a networking device.
To connect the RJ-45-to-RJ-45 interface cable to the T1/E1 ports:
1. Connect one RJ-45 end of the interface cable to the T1/E1 port on the front panel of the
gateway.
2. Connect the other RJ-45 end of the interface cable to the T1/E1 port of any networking device.
You can use either of the two BNC connectors or the BITS interface on the advanced clocking
module.
Note: Ensure a cable of 3m or less in length is used for the 10 MHz and 1PPS connectors.
To connect the BNC co-axial cable to the advanced clocking module:
1. Connect one end of the BNC co-axial cable to either the 1PPS BNC connector or the 10 MHz
BNC connector on the advanced clocking module.
2. Connect the other end of the BNC co-axial cable to the 10 MHz or 1PPS source network
equipment.
3. Please ensure the 10MHz / 1PPS Sources are 50 ohms LVCMOS / LVTTL (3.3v) compatible.
To connect the interface cable to the advanced clocking module:
1. Connect the RJ-45 end of the interface cable to the BITS interface on the front of the
advanced clocking module.
2. Connect the other end of the interface cable to the T1/E1 port of any networking device.
