Dual-Port Channelized T1/E1/ISDN PRI PIM

The Dual-Port Channelized T1/E1/ISDN PRI PIM (Figure 31 on page 57) is a multiflex interface card that allows you to configure a single interface as a channelized T1 interface or a channelized E1 interface. You can also configure ISDN PRI services on a channelized T1 or E1 interface. The channelized T1/E1/ISDN PRI interface supports up to 24 DS0 channels on a T1 interface and up to 31 DS0 channels on an E1 interface, in addition to supporting the features of regular (unchannelized) T1 and E1 PIMs. Each interface can be configured as a single clear-channel, fractionalized, or channelized interface.

NOTE: You cannot configure a channelized T1/E1/ISDN PRI interface through a J-Web Quick Configuration page.
