TDM Interface

The Time Division Multiplexor (TDM) processes channelized serial data such as T1 and E1. The data channels can be routed internally to the QUICC to any of the SCC or SMC control- lers. Each port can be configured to be either T1 or E1 at manufacturing. The TDM interface consists of:

•Three signals for the transmitter (L1TXD, L1TCLK, L1TSYNC)

•Three for the receiver (L1RXD, L1RCLK, L1RSYNC)

•Each direction has a data, clock and sync signal

The PmT1 supports two T1 TDM ports and the PmE1 supports two E1 TDM ports. The TDM signals are converted to T1 or E1 signaling by either the DS2151Q or DS2153Q transceivers and are routed to the front panel connectors (P1 and P2). Table 6-1and Table 6-3indicate which QUICC pins are dedicated to the TDM, and how the T1 or E1 signals from the trans- ceiver are routed to the connectors.

Configurations that route T1 or E1 out the P14 connector bypass the protection circuitry. The FCC Part 68 and UL1950 certification can be met by providing an external circuit pro- tection card.

The DS2153Q on the PmE1 requires specific initialization (reference Application Note 342;

DS2151, DS2153 Initialization and Programming, Dallas Semiconductor 102899):

1Set CCR2 to 0x04. This causes the framer to switch to RCLK if TCLK stops.

2Wait for at least 10 ms.

3Zero all of the framer registers except the LOTCMC bit that was set in step 1. This is important since the framer has no reset and cannot be guaranteed to be in an absolute known state after power-up.

4Configure the desired framer settings.

5Set the LIRST bit in CCR3

6Clear the LIRST bit in CCR3.

PMT1, PME1 specifications

The Emerson PME1 and PMT1 are advanced solutions in the realm of process management and automation, designed to enhance the efficiency and effectiveness of industrial operations. These devices play a crucial role in improving process control and providing comprehensive data analysis, which can lead to increased productivity and reduced operational costs.

The PME1 is characterized by its robust design and highly flexible architecture, allowing it to adapt to a variety of industrial environments. It integrates seamlessly with existing systems and offers advanced connectivity options to ensure that data flow is uninterrupted across different platforms. This feature is particularly important in modern industrial settings where data silos can inhibit operational efficiency.

The PMT1, on the other hand, focuses on real-time monitoring and telemetry. Its streamlined interface allows for quick access to key metrics, enabling operators to make informed decisions promptly. This is crucial in processes where timing is essential and minor delays can lead to significant financial losses. The PMT1 supports both wired and wireless communication protocols, ensuring that data is transmitted reliably irrespective of operational conditions.

One of the main features of both the PME1 and PMT1 is their integration of cutting-edge predictive analytics. With machine learning capabilities, these devices can analyze patterns and trends within the data, providing insights that can preemptively address potential issues before they escalate into significant problems. This predictive capability contributes to minimizing downtime and optimizing maintenance schedules, thus enhancing the overall lifecycle of equipment.

Another significant characteristic of the PME1 and PMT1 is their user-friendly interface. The intuitive design allows operators of all skill levels to navigate the systems with ease, minimizing training time and increasing overall productivity. With customizable dashboards, users can tailor their views to highlight the most relevant data for their specific operational needs.

In terms of security, both devices utilize advanced cybersecurity measures to protect sensitive data from unauthorized access. This is becoming increasingly important as industries rely more on digital solutions, and the potential risks associated with data breaches grow.

In summary, the Emerson PME1 and PMT1 are sophisticated tools designed for modern industrial applications, combining powerful features, advanced technologies, and essential characteristics. Their ability to provide real-time data analysis, ensure connectivity, and enhance predictive maintenance makes them invaluable for optimizing process management in various sectors. With a focus on user experience and data security, these devices are set to redefine efficiency and productivity in industrial operations.
