Channelized T1/E1/ISDN PRI Interfaces

Each port on a channelized T1/E1/ISDN PRI PIM is software configurable for T1, E1, or ISDN PRI service. Each channelized T1 or E1 interface can be configured as a single clear channel, or for fractional (NxDS0) or channelized operation, where N is channels 1 to 31 for an E1 interface and channels 1 to 24 for a T1 interface.

Each channelized interface can be configured as ISDN PRI B-channels and one D-channel or as a combination of T1 or E1 DS0 channels and ISDN PRI channels.

J-series ISDN PRI interfaces support the following switch types:

• ATT5E—AT&T 5ESS
• ETSI—NET3 for the United Kingdom and Europe
• NI2—National ISDN-2
• NTDMS100—Northern Telecom DMS-100
• NTT—NTT Group switch for Japan

Channelized T1/E1/ISDN PRI interfaces are configured through a configuration editor only.

A channelized T1/E1/ISDN PRI interface supports CoS configuration. For information about CoS features, see the J-series Services Router Advanced WAN Access Configuration Guide.
