System Requirements

To implement channelized IQ interfaces, your system must meet these requirements:

• JUNOS Release 6.2 or later for configuration of 64 DLCIs at the T1 channel level for channelized OC-12 IQ interfaces, 64 DLCIs at the E1 channel level for channelized STM-1 IQ interfaces, and 256 DLCIs at the T3 channel level for channelized DS-3 IQ interfaces
• JUNOS Release 6.2 or later for configuration of flexible Frame Relay, extended Frame Relay circuit cross-connect (CCC), and extended Frame Relay translational cross-connect (TCC) encapsulation types.
• JUNOS Release 6.0 or later for logical interface-level class of service on channelized STM-1 IQ interfaces, and APS/MSP on channelized OC-12 and STM-1 IQ interfaces
• JUNOS Release 5.7 or later for channelized STM-1 IQ interfaces
• JUNOS Release 5.7 or later for logical interface-level class of service on the channelized DS-3, E1, and OC-12 IQ interfaces
• JUNOS Release 5.6 or later for channelized DS-3, E1, and OC-12 IQ interfaces
• Two Juniper Networks M-series or T320 routers equipped with an Enhanced Type 1 or Type 2 Flexible PIC Concentrator (FPC)
