Dual-Port Channelized T1 or E1 PIM

The Dual-Port Channelized T1 or E1 PIM (Figure 27) 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.

You cannot configure a channelized T1 or E1 interface through a J-Web Quick Configuration page.

The Dual-Port Channelized T1 or E1 PIM provides the following key features:

• Onboard network processor
• Two-port channelization
• Interfaces that are software configurable as T1 or E1
• Clear-channel, fractional, and channelized operation
• Lower latency due to the addition of a Freescale processor
• Maximum MTU value of 4500 bytes (for channelized T1 or E1 interface)

  For a clear-channel T1 or E1 interface, the maximum MTU is 9150 bytes.

• 56-Kbps and 64-Kbps modes
• ANSI T1.102, T1.107, and T1.403 standards compliance
• G.703, G.704, and G.706 E1 standards compliance
• Independent internal and external clocking system
• Loopback, bit error rate test (BERT), T1 facilities data link (FDL), and long buildout diagnostics

Channelized T1 and E1 LEDs indicate PIM and port status. Table 30 describes the meaning of the LED states.
