Connecting Trunks
Connecting Trunks
The sections that follow contain basic information on how to set up the two types of trunks on the
IGX node. The two trunk types are FastPacket and ATM. The supported line types are OC3/STM1, T3,
E3, T1, Y1, and E1. The card sets described in this section are the network trunk module (NTM). The
enhanced universal switching module (UXM-E) is a dual-purpose, ATM cell-based card and has its own
section that includes information for trunk-mode configuration and port-mode configuration.
Setting Up a UXM-E
To set up a UXM-E attach cables and enter commands at the command-line interface (CLI). For detailed
information regarding the UXM-E, refer to the Cisco IGX 8400 Series Provisioning Guide.
You can specify the mode of the UXM-E through Cisco WAN Manager or the switch software CLI. The
UXM-E card set goes into the mode determined when you activate the first port. If you activate a logical
port to be a trunk by using the uptrk command, for example, the UXM-E goes into trunk mode. If you
use the upln command to activate a line as a User-Network Interface (UNI) port to customer premises
equipment (CPE) or an Network-to-Network Interface (NNI) to another network, the UXM-E goes into
port mode.
For a summary of commands used to bring up an IGX node, refer to the “IGX Configuration Summary”
section on page 59.
Bringing Up a UXM-E Trunk
If you are not familiar with precautions for card insertion, see the “Preparing the Cards” section on
page 3-1.
To attach the cables to a back card:
Step 1 Bring each cable through the opening at the top or bottom of the cabinet (whichever is appropriate) and
along the back of the IGX enclosure. See Figure 3-7.
Step 2 If the unit has the optional cable manager, you can use it to help route the cables. See Figure 3-7.
Step 3 Connect the cables to the connectors on the back card. See Figure 3-7.
