ADTRAN OCU DP OptionModule 1200068L1

Refurbished - 1 Year Warranty

The Office ChannelUnit Dataport (OCU DP) is one of the Option Modules available for use withtheADTRAN TSU 100. The OCU DP is an all-rate Office Channel UnitDataport. It provides signal conversionfrom any of the rates on thecustomer loop side to a single DS0 time slot. The OCU DP should beselectedfor use with the connection of DDS or Switched 56 DSU/CSUs orother equipment which utilizes a DDSinterface. The OCU DP provides aninterface between the T1 Multiplexer and a DSU/CSU over a 4-wireloop, up to18,000 feet in length of 26 AWG cable. This interface permits the combinationof DDS lines into asingle T1 stream.
