Electrical Coax
and Copper
Connectors
and Cabling
The DS3/E3/EC-1 Clear Channel and DS3/EC-1 Transmux cards are cabled using
standard coax cables with BNC or Mini-SMB connectors. Coax cables are connected to
the DS3/E3 electrical connector module (ECM) at the main backplane. The
10/100BaseTX, GbE TX plus 10/100BaseTX Combo, other GbE plus 10/100BaseTX
Combos, DS1, and E1 cards are cabled using standard twisted-pair copper cables with
Telco connectors. Twisted-pair cables are connected to 10/100BaseT, Ethernet
protection, or DS1/E1 ECMs at the main backplane.
The main backplane supports 1:N equipment protection, where N = 1 to 2, for electrical
TDM and Ethernet cards in cooperation with the ECM.
See the Traverse Cabling Guide, Chapter 2—“ECM Interface Specifications” for more
information on ECMs and electrical connector card specifications.
Shelf and Rack
Density
Each Traverse shelf provides high maximum switching capacities and interface
densities in a compact footprint to ensure optimal rack space utilization. The tables
below shows Traverse interface options, maximum switching capacities, and maximum
interface densities per shelf for interface cards and VT/VC cross-connect cards.
Important: The Traverse also supports 1:N DS3 Transmux equipment
protection groups for high-density optical transmux applications (using
STS1-TMX mode, where N = 3 to 12 for the 12-port DS3 Transmux cards
and N = 4 for the UTMX-24 and UTMX-48 cards. This application does
not require an ECM.
