T-SERV® II
The T-SERV® II CSU offers local management of T1 service lines. It meets all FCC and carrier requirements for a standard interface between the user and the network. The T-SERV II is NRTL listed to UL1950.
All basic CSU functions are contained in the T-SERV II CSU, including bipolar violation (BPV) correction, line build-out, loop-code generator for fault isolation, front-panel LED status indicators, test jacks, power options and automatic keep-alive signal generation. Its transparent operation passes the T1 bitstream unaltered.
All the basics
The Kentrox T-SERV II provides all the basic CSU functions.
Easy to install and use
The T-SERV II CSU can be online in as little as fifteen minutes. Just attach the power terminals and connect your T1 line (the dip switches are preset at the factory).
Diagnostic tools
Ten front panel LEDs offer a set of descriptive indicators of network status. Break, test and monitor jacks provide external access for T1 test equipment.
The T-SERV II automatically detects in-band loop codes, allowing your carrier to check the network through the CSU. With a toggle of the TEST switch, a far-end loop is initiated for end-toend network testing: by toggling the LOC switch, a near end terminal loop is activated for tests of the equipment side T1.
Stand-alone and plug-ins available
The T-SERV II CSU is available as a stand-alone unit or a plug-in version for medium- and high-density rack mounting options. The T-SERV II CSU standalone unit is suitable for desktop usage, or can be mounted on a wall with the included wall mounting brackets. The plug-in version can be installed in our 4-slot CSU mini-shelf or our high-density 12-slot CSU standard shelf.
The stand-alone version and our 4-slot CSU minishelf use rugged, industry-standard DA15 Network and Terminal interface connectors. An optional adapter to convert these DA15 interfaces to RJ48C jacks is also available.
The 12-slot CSU standard shelf uses either interface conversion panels or cables terminating in a stub configuration suitable for punch-down or wire wrap. Conversion panels are equipped with your choice of DA15 connectors, RJ48C jacks, or a combination of connectors. The conversion panels are connected to the main shelf via two cables, one for the Network Interface and one for the Terminal Interface. This flexible architecture allows the actual CSU interfaces to be located up to 200 feet from the CSU shelf, mounted directly above and below the shelf for front access, or mounted immediately behind the shelf for rear access.
When installed in our 4-slot mini-shelf or 12-slot standard shelf, these plug-in CSUs can be hotswapped. T-SERV II plug-in CSU cards can also co-exist in the same shelf as the intelligent T-SMART plug-in CSU.
