Define BESTFlow Signaling Protocol (BSP)
Unique framing software that transports up to 160 of any type of voice, fax, VoIP, secure voice or data modem calls into the payload of a single UDP IP packet for transmission over satellite or terrestrial links via layer 3 IP routing
ID the purpose of the Voice Exchange 900 (VX-900)
Prepares T1 circuits for interface with multiplexing equipment and offers the capability to compress circuit data rates as well as fractionalize T1 circuits to conserve bandwidth across transmission links
-
Provide additional connections to allow for greater redundancy on your CSN
ID the purpose of the Secure Relay Codec
Provide the VX-900 with the ability to compress secure telephone calls at a data rate of 9.6 Kbps per channel
ID the purpose of the Secure Relay Codec
Provide the VX-900 with the ability to compress secure telephone calls at a data rate of 9.6 Kbps per channel
Identify the number of Trunk Level One (T1) ports with which the Voice Exchange 900 (VX-900) Remote Subscriber Module (RSAM) variant is equipped
Two T1/E1 ports
Identify the number of Trunk Level One (T1) ports with which the Voice Exchange 900 (VX-900) Deployable End Office Suite (DEOS) variant is equipped
Eight T1/E1 ports
Identify the number of serial interfaceswith which the Voice Exchange 900 (VX-900) Remote Subscriber Module (RSAM) variant is equipped
Four serial ports
Identify the number of Ethernetports with which the Voice Exchange 900 (VX-900) Remote Subscriber Module (RSAM) variant is equipped
Two Ethernet ports
Identify the number of serialinterfaces with which the Voice Exchange 900 (VX-900) DEOSvariant is equipped
Four serial ports
Identify the number of Ethernetports with which the Voice Exchange 900 (VX-900) DEOSvariant is equipped
Two Ethernet ports
Identify the purposeof a Voice Exchange Node Identification Number (VX Node ID), per Tri-MEF Standard Operating Procedures (SOP)
ID individual VX900 media gateways within a voice network for proper traffic routing
Identify the Marine Corps standard used to create a Voice Exchange Node Identification Number (VX Node ID)
- Eight digit number expressed in four groups of two hex digits. E.g. 34:04:00:00
- If switchboard HMX code is 3440, VX Node ID would be 34:40:00:00

Identify the purpose of the Deployable End Office Suite (DEOS)
Designed to provide basic voice circuit switching, subscriber access and call service attendant capabilities
Identify the total number of analogsubscribers supported by the Redcom High Density Exchange (HDX)
96
Identify the total number of Digital Basic Rate Interface (BRI S/T) loops supported by the DEOS
8
Identify the total number of digital trunk interfacessupported by the Redcom High Density Exchange (HDX)

Identify the method of placing secure phone calls using the Redcom High Density Exchange (HDX)
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
Identify the common methods used to extend digital trunks from the Redcom High Density Exchange (HDX)
- Identical to RSAM methods
- Only difference is that the DEOS has a DSL multiplexer (DSLAM) to assist in trunk extension via DSL
Identify the purpose of the Loop Start Ring Down (LSRD) trunk within the DEOS
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
Identify the subcomponents of the Deployable End Office Suite (DEOS)
- 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
Identify the total number of Modular Switching Units (MSUs) with which the Redcom High Density Exchange (HDX) is equipped

Define Precedence
Designation assigned to a phone call by a caller to indicate to communications personnel/equipment the relative urgency of the call
Identify the five levels of Precedence
- Routine
- Priority
- Immediate
- Flash
- Flash Override
Define Multi-Level Precedence Preemption (MLPP)
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
Identify the method of preemption utilized within the Marine Corps
Ruthless preemption is currently the only preemption method authorized within each MEF
Define toll restriction
To curb a telephone user’s ability to make long distance calls.
