Identify in writing the communications symbol used to represent the Tactical Access Concentrator 300 (TAC-300)

Answer 10

Hexagon with “TAC-300” in the center

Question 11

E07

Define in writing Symmetric/Asymmetric Trunk (SA-TRK)

Answer 11

Medium by which a call leaves the node and enters the network; supports efficient transport of one-way and two-way calls between nodes.

Question 12

E07

Define in writing the network employment configurations available while employing a Promina-based multiplexer

Answer 12

Promina-based multiplexer networks can be established in a point-to-point or point-to-multipoint configuration.

Question 13

E07

Define in writing the number of T-1s that the AN/TTQ-5 Deployable Integrated Transport Suite (DITS) can compress with its standard PrimeVoice Server (PVS-12) card complement

Answer 13

3 T-1s can be compressed by the DITS in its standard configuration (two PVS/12 cards are required to compress one T-1)

*The PVS-12 Card allows for compression of voice calls. Each PVS-12 can compress 12 Digital Signal Zeros (DS0) to 16 Kbps per channel using the G.728 codec. Six PVS-12 cards are provided to ensure that 50% of the T-1 DS0s can be compressed. This method of compression allows secure STU-III and STE calls to pass uncompressed in a digital format through the network. The PVS-12s are located in slots 4 through 6 of DITS-1 and slots 14 through 16 of DITS-2.

Question 14

E07

Define in writing the number of T-1s that the AN/TTQ-5 Deployable Integrated Transport Suite (DITS) can compress with its standard PrimeVoice Server (PVS-12) card complement

Answer 14

3 T-1s can be compressed by the DITS in its standard configuration (two PVS/12 cards are required to compress one T-1)

*The PVS-12 Card allows for compression of voice calls. Each PVS-12 can compress 12 Digital Signal Zeros (DS0) to 16 Kbps per channel using the G.728 codec. Six PVS-12 cards are provided to ensure that 50% of the T-1 DS0s can be compressed. This method of compression allows secure STU-III and STE calls to pass uncompressed in a digital format through the network. The PVS-12s are located in slots 4 through 6 of DITS-1 and slots 14 through 16 of DITS-2.

Question 15

E07

Define in writing the number of high speed data connections that the AN/TTQ-5 Deployable Integrated Transport Suite (DITS) can process with its standard High Speed Data-2B (HSD-2B) card complement

Answer 15

10 high speed data circuits may be connected to the DITS in its standard configuration.

The HSD-2B card allows the DITS to connect to Defense Video Services, SIPRNET, and NIPRNET at data rates up to 8,192 Kbps. The HSD Card is located in slots 6 and 7 of DITS-1 and slots 17 through 19 of DITS-2. Each card has two ports.

Question 16

E07

Define in writing the number of T-1s that the AN/TTQ-5 Deployable Integrated Transport Suite (DITS) can process with its standard Primary Rate Card (PRC) complement

Answer 16

The DITS can support 6 T-1s (2 T-1 ports per card) in its standard configuration.

The PRC voice module consists of a PRC front card and a DS-1 interface card that supports the T-1 digital voice interface. In the DITS, the PRCs provide two T-1 (CAS or PRI) interfaces. The PRC allows connection of the DITS to the Defense Switched Network (DSN), Public Switched Telephone Network (PSTN), RSAMs, and DEOS. The PRC is located in slot 9 of DITS-1 and slots 21 and 22 of DITS-2.

Question 17

E07

Define in writing the number of Symmetric/Asymmetric Trunks (SA-TRK) that the AN/TTQ-5 Deployable Integrated Transport Suite (DITS) can process with its standard Symmetric/Asymmetric Trunk (SA-TRK) card complement

Answer 17

The DITS can support a total of three SA-TRKs at up to 8,448 Kbps in its standard configuration.

The SA-TRK cards provide the capability to have trunks with either the same transmit and receive data rates (symmetric) or different transmit and receive data rates (asymmetric). It provides symmetric and asymmetric trunking rates of 16 Kbps – 8,448 Kbps for Promina 400. In the DITS configuration, the SA-TRK cards provide WAN trunks or lateral links to other co-deployed units. The SA-TRK Card is located in slots 10 and 11 of DITS-1 and slot 23 of DITS-2.
