Chapter 6 Cisco IGX 8400 Series Data Service
Data Service Provisioning
Data Service Provisioning
This section provides information on how to provision data service on an IGX node. Information in this
section applies to the HDM and LDM cards. For more information on these cards, see the “High-Speed
Data Module” section on page 2-76 and the “Low-Speed Data Module” section on page 2-81 in
Chapter 2, “Cisco IGX 8400 Series Cards.”
Tip For information on using the UVM, CVM, and URM to provision data service, see Chapter 7,
“Cisco IGX 8400 Series Voice Service.” For information on using the UFM and FRM to provision data
service, see Chapter 9, “Cisco IGX 8400 Series Frame Relay Service.”
Before provisioning data service, you should perform basic configuration on the node, set up a trunk.
When provisioning data service, you will complete the following tasks:
1. Set up a data connection (see the “Setting Up a Data Connection” section on page 6-2).
2. Apply an interface control template to the data channel (see the “Configuring an Interface Control
Template” section on page 6-3).
3. Configure remaining channel parameters as necessary.
– Set up data frame multiplexing (DFM—see the “Enabling DFM on a Data Channel” section on
page 6-4).
– Set up embedded EIA (see the “Enabling Embedded EIA on the LDM” section on page 6-4).
4. Add the data connection to the circuit line.
Setting Up a Data Connection
Before setting up a data connection, you must configure the node, trunks, to be used for the data
connection. For information on configuring the node, see “Cisco IGX 8400 Series Nodes.” For
information on configuring a trunk, see “Cisco IGX 8400 Series Trunks.”
Table 6-1 Data Service Connections Supported on the IGX
Cards Connection Connection Type and Description
UVM, CVM Voice connection PCM or 64 kbps transparent data connections.
HDM, LDM Data connection Transparent bit stream, with only one connection per channel.
Data frame multiplexing (DFM) can be used to suppress
repetitive patterns to improve bandwidth efficiency for
128 kbps or slower connections.
UFM, FRM Frame forwarding
connection
Frame forwarding for bit-oriented protocols (HDLC, SDLC and
X.25/LAP-B).
Note Flags are not transmitted.
