Overview of TR Switching Circuit Sample Clauses

Overview of TR Switching Circuit. ‌ 2.1. A quarter wave circuit is a duplexer to deliver the transmission pulse to the antenna and the returned NQR signal to the reception circuitry. The intensity of the transmission pulse sometimes reaches thousands of volts that is much larger compared to the received NQR signal which is as weak as the thermal noise. As the weaker signal is of interest, the reception circuit including the reception amplifier must be highly sensitive, and the reception circuitry must be protected during the transmission phase. The duplexer is required to be able to decouple the reception circuitry during the transmission. A quarter wave cable or a quarter wave circuit operates to switch the impedance during transmission and reception when used in combination with the cross diodes. The impedance condition is ZiZo = |Z|2 where Zi is the input impedance, Zo is the output impedance, and Z is the characteristic impedance of the λ /4 cable/circuit. As Zi and Zo are inversely proportional, the resonance circuit and the reception cross diodes are closed to conduct low impedance during the transmission, and the impedance on the opposite side of the λ / 4 cable/circuit is high, isolating the reception system. If a quarter wave cable is actually used, a cable of several tens of meters is required for low frequency NQR measurement, so a π-circuit is often used instead of the cable. In this work, the system is not matched to 50 Ω hence this quarter wave circuit is not used. The cross diodes allow current to flow only when a voltage higher than the threshold voltage is applied across the diodes. This prevents the excitation pulse from flowing to the reception amplifier at the time of transmission and separates the transmission amplifier at the time of reception. It is used to protect the circuitry and reduce noise.

Upon appointment of the arbitrator, the appealing party shall, within five (5) days after notice of appointment, forward to the arbitrator, with a copy to the School Board, the submission of the grievance which shall include the following: 1. The issues involved. 2. Statement of the facts. 3. Position of the grievant. 4. The written documents relating to Section 5 of the grievance procedure.

  • Detailed Description of Services / Statement of Work Describe fully the services that Contractor will provide, or add and attach Exhibit B to this Agreement.

  • SERVICE LEVEL DESCRIPTION The Fund Accounting Agreement is hereby amended by deleting the Service Level Description attached thereto and replacing it in its entirety with the Service Level Description attached hereto.

  • Line Information Database (LIDB 9.1 BellSouth will store in its Line Information Database (LIDB) records relating to service only in the BellSouth region. The LIDB Storage Agreement is included in this Attachment as Exhibit C. 9.2 BellSouth will provide LIDB Storage upon written request to <<customer_name>>’s Account Manager stating a requested activation date.

  • Line Information Database LIDB is a transaction-oriented database accessible through Common Channel Signaling (CCS) networks. For access to LIDB, ONS must purchase appropriate signaling links pursuant to Section 10 of this Attachment. LIDB contains records associated with End User Line Numbers and Special Billing Numbers. LIDB accepts queries from other Network Elements and provides appropriate responses. The query originator need not be the owner of LIDB data. LIDB queries include functions such as screening billed numbers that provides the ability to accept Collect or Third Number Billing calls and validation of Telephone Line Number based non-proprietary calling cards. The interface for the LIDB functionality is the interface between BellSouth’s CCS network and other CCS networks. LIDB also interfaces to administrative systems.

  • Voice Information Service Traffic 5.1 For purposes of this Section 5, (a) Voice Information Service means a service that provides [i] recorded voice announcement information or [ii] a vocal discussion program open to the public, and (b) Voice Information Service Traffic means intraLATA switched voice traffic, delivered to a Voice Information Service. Voice Information Service Traffic does not include any form of Internet Traffic. Voice Information Service Traffic also does not include 555 traffic or similar traffic with AIN service interfaces, which traffic shall be subject to separate arrangements between the Parties. Voice Information Service Traffic is not subject to Reciprocal Compensation charges under Section 7 of the Interconnection Attachment. 5.2 If a ECI Customer is served by resold Verizon dial tone line Telecommunications Service or a Verizon Local Switching UNE, to the extent reasonably feasible, Verizon will route Voice Information Service Traffic originating from such Service or UNE to the appropriate Voice Information Service connected to Verizon’s network unless a feature blocking such Voice Information Service Traffic has been installed. For such Voice Information Service Traffic, ECI shall pay to Verizon without discount any Voice Information Service provider charges billed by Verizon to ECI. ECI shall pay Verizon such charges in full regardless of whether or not ECI collects such charges from its Customer. 5.3 ECI shall have the option to route Voice Information Service Traffic that originates on its own network to the appropriate Voice Information Service connected to Verizon’s network. In the event ECI exercises such option, ECI will establish, at its own expense, a dedicated trunk group to the Verizon Voice Information Service serving switch. This trunk group will be utilized to allow ECI to route Voice Information Service Traffic originated on its network to Verizon. For such Voice Information Service Traffic, unless ECI has entered into a written agreement with Verizon under which ECI will collect from ECI’s Customer and remit to Verizon the Voice Information Service provider’s charges, ECI shall pay to Verizon without discount any Voice Information Service provider charges billed by Verizon to ECI. ECI shall pay Verizon such charges in full regardless of whether or not ECI collects such charges from its own Customer.
