Dual-Port Channelized T1/E1/ISDN PRI PIM

The Dual-Port Channelized T1/E1/ISDN PRI 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. 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.

The Dual-Port Channelized T1/E1/ISDN PRI PIM provides the following key features:

Onboard network processor
Two-port channelization
Interfaces that are software configurable as T1 or E1 channels or ISDN PRI B-channels
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) and 4098 bytes (for ISDN PRI services)

Note: 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

For pinouts of cable connectors for channelized T1/E1/ISDN PRI PIMs, see ISDN RJ-45 Connector Pinout.

To install or remove a PIM, see Replacing a PIM.

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

Note: The STATUS LED displays channelized T1 or E1 port activity and alarms only. It does not display ISDN PRI B-channel or D-channel status.

Table 30: LEDs for Channelized T1/E1/ISDN PRI PIMs

Label	Color	State	Description
ONLINE	Green	On steadily	PIM is online and operational.
ONLINE	Unlit	Off	PIM is not online.
STATUS	Green	On steadily	Port is online with no alarms or failures, and the physical layer is active.
	Red	Online	Port is active with a local alarm. The router has detected a failure and the physical layer is inactive.
	Yellow	Online	Port is online with alarms for remote failures.
	Unlit	Offline	Port is disabled.

For alarms, see the configuring and monitoring alarms information in the J-series Services Router Administration Guide.
