DMD15/DMD15L IBS/IDR Satellite Modem Operation 3.2 Universal Interface Module (UIM) The Universal Interface Module (UIM) is a field-replaceable module that plugs into the rear of the DMD15/DMD15L. The UIM provides the interconnection points (J3 - J8) for Terrestrial Data and Clock to the Modem. The UIM also contains a Connection Port for an Asynchronous Data Channel (J9) for use in Earth Station-to-Earth Station (ES-ES) communications.
Operation DMD15/DMD15L IBS/IDR Satellite Modem Figure 3-3. Universal Interface Modules (UIM) Functional Block Diagram 3.3 Synchronous Interface Synchronous Tx Data and Clock enters the UIM and is routed to either the RS-422, RS-232, or V.35 Receiver as the selected M&C Processor. The signals are then converted to an RS-422 balanced format and sent to the Baseband (BB) Processor Card.
DMD15/DMD15L IBS/IDR Satellite Modem Operation can be connected to the ‘Insert Data In’ Port where received data will overwrite ‘dropped on’ the T1/E1 Data Stream. The modified T1/E1 Data Stream will then exit the modem out of the ‘Receive Data Out’ Port. 3.5 Earth Station to Earth Station (ES-ES) Communications Port (Async Port J9) The UIM contains a selectable RS-232, or RS-485 Asynchronous Communications Port for EarthStation-to-Earth-Station Communications.

Operation DMD15/DMD15L IBS/IDR Satellite Modem 3.8 Baseband Processor Card The Baseband Processor Card (BB Card) contains two major subsystems⎯the Baseband Processing System and the Monitor and Control Subsystem. 3.8.1 Baseband Processing The Baseband Processor performs all of the functions required for an IBS/IDR Framing Unit, a Reed-Solomon Codec, an E1/T1 Drop and Insert System and a Turbo Codec.
DMD15/DMD15L IBS/IDR Satellite Modem Operation 3.8.3 Rx Baseband Processing The Receive Processor performs the inverse function of the Tx Processor. Data received from the satellite passes through the BB Loopback Circuit to the Reed-Solomon Decoder to the Deframer. The Deframer acquires the IBS/IDR frame, synchronizes the Reed-Solomon Decoder and extracts the received data and overhead from the frame structure, placing the data into the PD Buffer, sending the overhead data to the UIM.
Operation DMD15/DMD15L IBS/IDR Satellite Modem 3.9.4 Front Panel Interface The M&C operates the Front Panel, which includes a 2 x 12 backlit LCD, Indicator LEDs, and a Numeric Keypad. 3.9.5 Clock The time and date is kept in order to ‘time-tag’ system events. 3.9.6 Watchdog Timer The Watchdog Timer monitors the health of the M&C Subsystem. 3.9.7 Program Flash ROM The 512K of reprogrammable program ROM (expandable to 1 MB) is available to the M&C. 3.9.8 RAM 128K RAM (expandable to 512K) 3.9.
DMD15/DMD15L IBS/IDR Satellite Modem Operation 3.10.2 Demodulator The demodulator performs a complete digital implementation of a Variable-Rate Phase-Lock Satellite Receiver utilizing state-of-the-art digital signal processing techniques. The demodulator is capable of receiving nearly any modulation format. Signals enter the demodulator, are converted to baseband, split into ‘I’ In-Phase and ‘Q’ Quadrature Channels and digitized.
Operation DMD15/DMD15L IBS/IDR Satellite Modem 3.11.7 IDI: Insert Data In This clock source is only used as an external frame source selected in D&I Mode. If External Frame Source is selected, then IDI must be selected for the buffer clock. For this case, a Receive T1/E1 Trunk is input into J5 and a buffer clock is derived. 3.11.8 SCR: Serial Clock Receive This Receive Clock is recovered from the satellite’s receive signal from the satellite.
DMD15/DMD15L IBS/IDR Satellite Modem Operation 3.14 Loop Timing If loop timing is desired (i.e.; the modem timing is slaved to the far end master station), the modem clocks can be configured as follows: 3.14.1 Transmit (RS-422 or V.35 Interface) Set SCT Source to ‘SCR’. The Tx Terminal Equipment must clock the TX Data with the SCT Clock and return data and SCTE (Optional). If SCTE is returned to the modem from the terminal equipment, set TX CLK to SCTE.

DMD15/DMD15L IBS/IDR Satellite Modem Operation 3.15.1 Drop Only When Drop is enabled and Insert is disabled, the DMD15/DMD15L performs a drop-only function. Framed E1 or T1 Data is input via the Send Data In Port, the selected timeslots are dropped into the IBS frame structure, and the unaltered terrestrial data is output via the Send Data Out Port (refer to Figure 3-10). Figure 3-10. Drop Only 3.15.
Operation DMD15/DMD15L IBS/IDR Satellite Modem Figure 3-12. Insert Only with Internal Frame Source 3.16 Mode Selection The DMD15/DMD15L D&I can be easily configured to support several commonly used terrestrial data formats. For E1 Data, the user can choose between PCM-30, PCM-30C, PCM-31 and PCM31C. For T1 Data, the user can choose between T1-D4, T1-ESF, and SLC-96. The following paragraphs provide more information on the various mode selection capabilities of the DMD15/DMD15L. 3.16.
DMD15/DMD15L IBS/IDR Satellite Modem Operation 3.16.4 PCM-31C The PCM-31C Mode of Operation supports an E1 Interface with no Multiframe Alignment (MFAS) or Channel Associated Signaling (CAS). In addition, the Drop Function verifies the received terrestrial CRC checksum and the Insert Function calculates the required CRC checksum. The user may independently program ‘n’ timeslots to drop and ‘n’ timeslots to insert where ‘n’ = 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, or 30.

Maps always contain 30 entries, although, only the first “n” entries are relevant (see Table 4-5). The DMD15/DMD15L includes provisions to copy, change, and store the D&I transmit and receive maps directly from the Front Panel or via the remote M&C link. These maps are tables that are used to define and configure the D&I functions.

Any reference to the DMD15 in this document can be applicable to any one of these three modems. Control and status messages are conveyed between the DMD15 and the subsidiary modems and the host computer using packetized message blocks in accordance with a proprietary communications specification.
DMD15/DMD15L IBS/IDR Satellite Modem : User Interfaces The Source Identifier defines the multi-drop address origin. Note: All nodes on a given control bus have a unique address that must be defined. : The Destination Identifier serves as a pointer to the multi-drop destination device that indicates where the message is to be sent. : The Frame Sequence Number (FSN) is a tag with a value from O through 255 that is sent with each message.
User Interfaces DMD15/DMD15L IBS/IDR Satellite Modem Thus, the checksum is 00000101b; which is 05h or 5 decimal. Alternative methods of calculating the checksum for the same message frame are: 00h + 02h + F0h + 2Ah + 09h + 00h + 03h + DFh + FEh = 305h. Since the only concern is the modulo 256 (modulo 1 00h) equivalent (values that can be represented by a single 8-bit byte), the checksum is 05h.
DMD15/DMD15L IBS/IDR Satellite Modem User Interfaces The full handshake/acknowledgment involves a reversal of source and destination ID codes in the next message frame, followed by a response code in the field of the message packet from the equipment under control. If a command packet is sent and not received at its intended destination, a timeout condition can occur because a response message is not received by the packet originator.

DMD15/DMD15L/DMD15/DMD15LL/DMD15/DMD15LIBS/IDR Satellite Modem Maintenance Section 6 – Maintenance 6.0 Periodic Maintenance The DMD15/DMD15L modulator requires no periodic field maintenance procedures. Should a unit be suspected of a defect in field operations after all interface signals are verified, the correct procedure is to replace the unit with another known working DMD15/DMD15L. If this does not cure the problem, wiring or power should be suspect. There is no external fuse on the DMD15/DMD15L.
Maintenance DMD15/DMD15L/DMD15/DMD15LL/DMD15/DMD15LIBS/IDR Satellite Modem Masking alarms can cause undesirable modem performance. 6.2.1 Alarm Masks The user has the capability to ‘Mask’ individual alarms on the DMD15/DMD15L. When an Alarm is masked, the Front Panel LEDs and the Fault Relays do not get asserted, but the Alarm will still be displayed. This feature is very helpful during debugging or to lock out a failure that the user is already aware of. 6.2.2 Active Alarms 6.2.2.
