Chapter 3 Installing the Router
Connecting the MWR 1900 Router to a DC-Input Power Supply
This section describes the specifications of the Y-cable.
• T1/E1 Multiflex VWIC Y-cables should be made with 4 twisted-pair, shielded, 28-gauge cables.
• The cable length of each stub (from the RJ-48C connector to the junction point) should not exceed
3 inches (76 mm).
• The cable length from junction point to the patch panel is determined by the customer.
• All signals that propagate in the same direction must share the same twisted pair. For example, RX
TIP and RX RING must form a single twisted pair.
• All unused twisted pairs should be cut flush on both ends of the cable. Any unused wire in a twisted
pair where one wire is in use should be cut flush at both ends.
