Dual-Port Channelized T1 or E1 PIM
The Dual-Port Channelized T1 or E1 PIM (Figure 15) is a multiflex interface card
that allows you to configure a single interface as a channelized T1 interface or a
channelized E1 interface. The channelized T1 or E1 interface supports up to 24 DS0
channels on a T1 interface and up to 32 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 or E1 interface through a J-Web Quick
Configuration page.
