22
Q

Identify the purpose of the Deployable End Office Suite (DEOS)

A

Designed to provide basic voice circuit switching, subscriber access and call service attendant capabilities

23
Q

Identify the total number of analogsubscribers supported by the Redcom High Density Exchange (HDX)

A

96

24
Q

Identify the total number of Digital Basic Rate Interface (BRI S/T) loops supported by the DEOS

A

8

25
Q

Identify the total number of digital trunk interfacessupported by the Redcom High Density Exchange (HDX)

A

8

26
Q

Identify the method of placing secure phone calls using the Redcom High Density Exchange (HDX)

A

DEOS has no organic secure call capability, with the use of STE or OMNI line encryption device, users have the ability to make secure calls

27
Q

Identify the common methods used to extend digital trunks from the Redcom High Density Exchange (HDX)

A
  • Identical to RSAM methods

- Only difference is that the DEOS has a DSL multiplexer (DSLAM) to assist in trunk extension via DSL

28
Q

Identify the purpose of the Loop Start Ring Down (LSRD) trunk within the DEOS

A

Allows the DEOS to bring in a trunk from a local civilian or garrison telephone network pedestal, providing it with the ability to send and receive phone calls from the tactical telephone network out through the local telephone network infrastructure

29
Q

Identify the subcomponents of the Deployable End Office Suite (DEOS)

A
  • Redcom HDX with two shelves -MSU-0 and MSU-1
  • VX-900
  • DSLAM
  • UPS
  • VIB x11
  • Panasonic Tough Book x2
  • CSU/DSU x4 per DEOS
30
Q

31
Q

Define Precedence

A

Designation assigned to a phone call by a caller to indicate to communications personnel/equipment the relative urgency of the call

32
Q

Identify the five levels of Precedence

A
  • Routine
  • Priority
  • Immediate
  • Flash
  • Flash Override
33
Q

Define Multi-Level Precedence Preemption (MLPP)

A

System in military circuit switching networks which allows selected users to exercise preemption capabilities to seize circuits being used for lower-precedence calls in order to place their higher-precedence call

34
Q

Identify the method of preemption utilized within the Marine Corps

A

Ruthless preemption is currently the only preemption method authorized within each MEF

35
Q

Define toll restriction

A

To curb a telephone user’s ability to make long distance calls.

36
