Juniper Networks G10 CMTS manual 110, On page 54 for port labeling

Cable an HFC Connector Module or SIM

•	One possible deployment scenario for the upstream is to attach one node per upstream port
•	and to turn on one upstream interface per node. If one of the nodes reaches capacity due to
•	high penetration or heavy usage of bandwidth-intensive services, you can provision another
•	interface on that port.
•
•	To cable the downstream ports, following this procedure (see Figure 18 on page 51 and
•	Figure 20 on page 54 for port labeling):
•
•	1. Select the first node in the cable plant for assignment to the first of four downstream
•	ports.
•
•	2. Connect the coaxial cable associated with the first node to the F-connector labeled DS0
•	on the HFC Connector Module or the SIM.
•
•	3. If applicable, select the second, third, and fourth nodes in the cable plant for assignment
•	to the remaining three downstream ports.
•
•	4. If applicable, connect the coaxial cables associated with the second, third, and fourth
•	nodes to the F-connectors labeled DS1, DS2, and DS3 on the HFC Connector Module or
•	the SIM.
•
•
•		When you tighten a coaxial cable onto an F-connector, use
•
		a 7/16 inch torque wrench to apply torque according to
•
		SCTE standards.
•
•
•
•	To cable the upstream ports, follow this procedure:
•
•	1. Select the first node in the cable plant for assignment to the first of four upstream ports.
•
•	2. Connect the coaxial cable associated with the first node to the F-connector labeled US0
•	on the HFC Connector Module or the SIM.
•
•	3. If applicable, select the second, third, and fourth nodes in the cable plant for assignment
•	to the remaining three upstream ports.
•
•	4. If applicable, connect the coaxial cables associated with the second, third, and fourth
•	nodes to the F-connectors labeled US1, US2, and US3 on the HFC Connector Module or
•	the SIM.
•
•	5. We recommend that you use cable organizers to dress and route all coaxial cables to
•	avoid obstructing the rear connections of the CMTS (see Figure 35 on page 112).
•
•
•		A node can represent a single node or multiple nodes that
•
•		are combined.
