Before a port or SCADA bridge can be configured, the adapter card slot must be preprovisioned with an allowed adapter card type (for a SCADA bridge, the only type allowed is isc, for the Integrated Services card).
Preprovisioning recommendations (for ports only) include:
Ethernet
Configure an access port for customer-facing traffic on which services are configured.
Configure a network port for uplink traffic.
An encapsulation type must be specified to distinguish services on the access port. Encapsulation types must also be specified for network ports. By default, the encapsulation type for Ethernet ports in network mode is null.
SONET/SDH
SONET/SDH can be used only when configuring an OC-3 or OC-12 SONET path on an appropriate adapter card.
Configure a network port or channel to participate in the service provider transport or infrastructure network.
To configure a SONET path, see Configuring SONET/SDH Port Parameters.
Channelized
Channelized ports can be configured on the following adapter cards and modules:
16-port T1/E1 ASAP Adapter card
32-port T1/E1 ASAP Adapter card
2-port OC3/STM1 Channelized Adapter card
4-port OC3/STM1 / 1-port OC12/STM4 Adapter card
8-port Voice & Teleprotection card (access mode only)
8-port C37.94 Teleprotection card (access mode only)
8-port FXO Adapter card (access mode only)
6-port FXS Adapter card (access mode only)
4-port DS3/E3 Adapter card (DS3 ports only)
12-port Serial Data Interface card (access mode only)
6-port E&M Adapter card (access mode only)
4-port T1/E1 and RS-232 Combination module
Configure an access port for customer-facing traffic on which services are configured.
Configure a network port for uplink traffic.
An encapsulation type must be specified to distinguish services on the access port or channel. For network mode, the encapsulation type is set to ppp-auto and cannot be changed.
