CABINET CONFIGURATIONS
Three basic cabinet configurations are offered as explained below. Expansion kits are provided to increase the capacity
of each configuration to up to three GranDSLAM 4200 DSLAMs. Kits are also provided for fan and filter replacement and
for pole or wall mounting brackets.
Model numbers are of the form 43WX-P1-Y0Z, where:
• W is the DSL type (1 for ReachDSL, 2 for ADSL, 3 for ADSL Annex B, 7 for SHDSL)
• X is the uplink type (1 for T1 ATM, 2 for E1 ATM, 3 for 8-port T1/E1 IMA, 9 for 10/100/1000BaseT/GigE fiber)
• Y is the power type (1 for externally-fed –48/–60 VDC, 2 for AC, 3 for line power)
• Z is the splitter option (0 for 900 ohm, 1 for 600 ohm)
The three basic cabinet configurations are:
Model 1 (Feature Number 43xx-P1-10x) - Cabinet to be used at existing remote terminal sites, where the RT can
supply –48 VDC power. This model will be wired for one GranDSLAM assembly.
Model 2 (Feature Number 43xx-P1-20x) – Cabinet to be used where AC power is available. This model will be
wired for one GranDSLAM assembly and will include an AC load center and a –48 VDC rectifier.
Model 3 (Feature Number 43xx-P1-30x) – Cabinet to be used where AC power is not available. Power to the cabinet
will be provided by up to 25 common pairs. The tips and rings of the pairs are bussed together and fed to a DC-DC
converter, which provides the –48 VDC power to the GranDSLAM assemblies. The input voltage to the DC-DC converter
is 90 to 400 VDC. This model will be wired for one GranDSLAM assembly.
