The Aeroflex/IFR/Marconi 2968 TETRA Radio Test Set Version 3.2, isdesigned to provide faster, more comprehensive and easier to use testsfor the routine terminal maintenance and repair operations normallyundertaken by the emergency services and managed terminal suppliers.Automatic receiver (BER) testing using TTRF loopback enables the Rxsensitivity of the terminal to be tested automatically without the needfor special test programs and interface connections or userintervention. The TETRA Equipment Identity (TEI) is obtainedautomatically from the terminal and included in the test results toidentify the terminal under test, avoiding the risk of human error. Theterminal's Power Class and Receiver Class are also obtainedautomatically so that the test program can apply the appropriate testlimits. Up to six different types of call set-up and clear down can bespecified in a built in test program to suit the capabilities of theterminal type to be tested and the degree of functional testingrequired. Group calls, private calls and telephone calls can be includedthat are both mobile originated and mobile terminated. Version 3.2 alsoincludes extended TIP coverage including support for additional TIPv3Part 1 Core Services, TIPv4 Part 6 Air Interface Migration and TIPv4Part 8 Testing Requirements. TIPv3 Part 1 Core Services are supported inaccordance with specification TTR 001-1 v3.0.13 including Registration,Individual Call, Group Management, Group Call, Emergency Call, CellRe-Selection, SDS Status and Telephone Call. Particular enhancementsinclude: Multiple Group Attachments with up to 40 talk groups aredisplayed to determine that the terminal has been correctly configuredwith the required groups and scanning priorities.
# Group Modifications are displayed to check the ability of the terminalto attach or detach groups or change the scanning priority of a group.
# Status Messages are displayed to check the terminal configuration.Defined status values are decoded, with status address: SSI (private),GSSI (group) or ESN (phone).
# DTMF Over-Dial digits are displayed to check that the terminalconfiguration enables the use of DTMF signalling during a telephonecall. SDS-TL Text Messages are supported in accordance with TTR 001-2v1.0.11 (TIPv3 Part 2). The enhancements include:
# Sending and Receiving Text Messages that are user configurable up to 120 characters.
# 7-bit GSM (Phone Mode) and 8-bit TETRA (Private Mode) coding schemes.
# Message Time Stamping is automatically included, if required.
# Short Form Message Reports can be sent and received when requested.TIPv4 Part 6 Air Interface Migration is supported in accordance with TTR001-6 v1.0.0 enabling TETRA terminals that support migration toregister to the IFR 2968 regardless of whether the country code (MCC)and network code (MNC) configured in the terminal match thecorresponding parameters configured in the test set. This simplifiestesting, particularly in cases where the terminal configuration is notknown. Test Mode Registration and TETRA Test mode (TT) RF Loopback aresupported in accordance with TTR 001-8 v1.0.0 (TIPv4 Part 8) enablingTETRA terminals which support TETRA Test mode to supply their EquipmentIdentity, Power Class and Receiver Class for test automation, as well asperforming RF Loopback for measuring receiver sensitivity using the BitError Rate (BER) and Message Erasure Rate (MER).
