Cisco NM-4B-U 2600/3600 NM-4B-U 4-Port BRI-U with Handle
The 4- and 8-port ISDN BRI network modules provide various port densities for ISDN BRI connectivity. The optional, integrated NT1 allows consolidated customer premises equipment (CPE) to provide multifunction dial access server, router, and other capabilities within power branch office environments.
Four versions of ISDN BRI network modules are available. Each 4- and 8-port module has the option of an S/T interface or an onboard NT1 for each port. Local static RAM (SRAM) is used for buffer descriptors and input queues. The 4-port module cannot be field-upgraded to the 8-port module. When all eight BRI ports run continuous data (144 kbps each) and 50-byte packets, the maximum performance possible is 5760 pps, and an aggregate full-duplex data rate of 2.3 Mbps.
