STE Line Ordering

• STE Secure Terminal Equipment
• Sets are not on WITS2001 contract, but
  Service_at_once will provision lines to support
  these sets.

3
Secure Terminal Equipment

• Rule number 1 A STE is a security device
  first and a telephone second.
• A STE acts more like a piece of data CPE. In
  fact, the ISDN configuration is the same that is
  used to configure a line used for one model of a
  CISCO router.
• Preferred mode of operation is National ISDN.
• Feature development is being done for the
  National configuration. Enhancements are also due
  for the 8510 emulation mode.

4
Secure Terminal Equipment

• A STE can be configured for one DN per unit or
  two directory numbers (DNs) per unit (supports
  secure casual conference and bonded data
  transmission at 128K).
• A STE is always a multipoint (MP) configuration
  even when only one DN is assigned. A STE
  requires a Service Profile Identifier (SPID) to
  function.
• A STE must be the only piece of equipment on the
  MP pipe.

• Set up for V/D on the B1 channel and NONE on the
  B2 channel on each equipped number.
• Why?
• The set only uses one channel per DN. In the
  secure mode, it establishes a data call to the
  other unit. In the non-secure voice mode, it
  uses the B channel for a normal voice call. The
  set cannot function in the secure mode and
  non-secure mode concurrently.
• In the two DN mode, the set establishes a second
  data call using the second DN B channel for a
  secure casual conference or bonded data
  transmission.

• As the order enterer, you need to input the class
  of service and the PIC for each of the assigned
  directory numbers
• The IOC will populate the rest of the line
  parameters to support the STE
• You can add additional features to the STE..but
• Remember Rule number 1
• Security Device First
• Telephone Second

Service_at_once - STE 5ESS - 8510 Emulation Mode

• Custom ISDN terminal type D
• Multipoint SHDNIPO/SHDNIPM
• On each ISDN pipe B1V/D B2None
• This configuration does support visual MWI.
• This is not a plug and play replacement for a
  Lucent 8510. Operation is unpredictable at
  times. Work is being done to enhance.
• Keys 9 and 10 do not have lamps/indicators.
• Call appearances assigned beyond key 10 will
  cause the STE to reset when they ring.
• Remember Rule number 1.

13
Service_at_once - STEHelpful Hints

• When using 2 DNs, cross-reference each DN in the
  remarks section in Service_at_once.
• STE lines can be provisioned National ISDN even
  if other office lines are Custom ISDN.
• Shared call appearances are only supported on
  STEs with 8510 Emulation.
• Reference the Secure Wired Products Web Site (see
  next page) for information about STEs and PBXs /
  PRIs.
