Ameritec CRS-D

The Ameritec CRS-D Crescendo is a high-volume call generator designed for simulating telephony subscribers and testing telecommunication network equipment. This versatile instrument is engineered to support the development and execution of complex call scenarios and interactive applications under significant call loads, making it suitable for dedicated lab environments. The Ameritec CRS-D Crescendo facilitates the testing of switches, wiring, and other telecommunications infrastructure by generating artificial phone traffic. It can simulate a wide range of subscriber actions through user-defined call scripts and line protocols, allowing for tailored test scenarios for development, production, quality assurance, and regression testing.

### Technical Specifications

* **Product Name:** Ameritec CRS-D Crescendo
* **Product Type:** Digital Call Generator
* **Primary Function:** Simulates telephony subscribers placing calls into the network for testing purposes.
* **Simultaneous Call Capacity:**
* Supports up to 8 T1 interfaces, with each T1 having 24 channels, enabling the generation of up to 192 simultaneous calls.
* When grouped with other Ameritec Crescendo, Niagara, or Squirt units, it can simulate thousands of telephony subscribers.
* **Supported Interfaces and Protocols:**
* Analog circuits (loop start lines)
* T1 (1.544 Mbps PCM T1 CAS trunks)
* Provides interface for eight (two groups of four) 1.544 Mbps T1 CAS trunks.
* E1 (2.048 Mbps PCM E1 CAS trunks)
* Provides interface for eight (two groups of four) 2.048 Mbps E1 CAS trunks.
* Basic Rate ISDN (BRI)
* Primary Rate ISDN (PRI)
* Available option, provided in four-trunk increments.
* SS7/C7 signaling
* Available option, provided in four-trunk increments.
* Dedicated Common Channel Signaling processor for SS7 signaling links.
* Northern Telecom EBS (P-phone)
* **Call Scripting Capabilities:**
* Independently controlled subscriber actions via user-programmed Call Scripts.
* Call Scripts include capabilities for:
* Signaling
* Dialing
* Voice over Packet (VoP)
* Digit decoding
* Tone sending
* Path verification
* Voice replay (up to 64 two-second messages, with limitations on ISDN-PRI and SS7 options)
* Tone receive
* Scripts define calling patterns and can simulate virtually any action a live caller can perform.
* Scripts can simulate multiple subscribers for testing multi-party calls (e.g., conference calling).
* Ameritec ScriptMate allows for graphical development of test scripts via Call Flow Diagrams.
* **Software and Control:**
* Ameritec FeatureCall GUI (Windows-based Graphical User Interface) for creating test systems, defining test parameters, and running test cases.
* Control of up to 32 Crescendo units over a TCP/IP LAN via FeatureCall.
* **Signal Processing:**
* Each group of lines (e.g., 16 lines) is served by four dedicated DSPs for call progress tone identification, dual-tone digit sending/detection, and voice path verification.
* Each local DSP can service all circuit-switched voice channels in a single trunk simultaneously.
* For Primary Rate ISDN option, each trunk line is served by a Common Channel Signaling processor for all signaling and packet-switched data testing.
* **Physical Characteristics:**
* Full 4U rack unit size.
* May be designed for a 23″ telecom rack rather than a standard 19″ rack.
* Front Panel: Features LED status lights for T1 circuits, system signaling LEDs, and a vented panel.
* Rear Panel:
* 2x 25-pair Amphenols (RJ21) for T1 connections.
* Management ports likely include: RJ45 network port, DB25 RS-232 serial port, Aux jack (DE-9 pin), Audio jack (DE-9 pin).
* CRS-De version may include BNC jacks for E1 connectivity.
