Analog Services Unit II

The ASU II is a common platform to deliver analog trunks and extension services to all markets
(replacing the many variants of ASU and the Universal ASU). It comprises a chassis with two
card slots. The two card variants that are supported are a 16-extension or ONS (On-Premise
Station) card slot and a 4-trunk plus 12-extension card. Any card can fit into any slot and the
cards can be inserted while the unit is operational.
The ASU II chassis can support up to 32 ONS phones, up to eight LS trunks, Music on Hold,
or Loudspeaker paging depending on how the unit is configured with peripheral cards.
The 4 + 12 port combo card supports:
• 12 On-Premise Station (ONS) Lines for analog phones
• Four Loop Start (LS) trunks for analog connection to a central office
• Four System Fail Transfer (SFT) relays that provide direct connection between an analog
telephone and a Loop Start trunk in the event of a system or power failure.
The North American version supports Custom Local Access Signaling Services (CLASS) on
the ONS circuits. CLASS allows the 3300 ICP system to pass Calling Line ID digits and CLASS
name information to display sets that support Caller ID functionality.
The 16 port ONS card supports:
• 16 On-Premise Station (ONS) Lines for analog phones..
Note: CLASS trunks are not currently supported.
Note: The ASUs support only DTMF telephones; pulse or rotary dial phones are not
supported.
Note: The Cx and CXi Controllers ship with embedded analog capability provided by
one or two analog boards: the Analog Main Board (AMB) and the optional Analog Option
Board (AOB) for expansion.
Note: The CX and CXi controllers do not support Analog Services Units.
