2-70 Section 060-INDP-111 System Description System Description - Software The BMC is an intelligent peripheral of the associated Switching System, capable of making decisions without guidance from the Switching System’s Common Control Processor/Memory Complex. The BMC activities are controlled by software resident in the BMC. The internal architecture of the BMC is closely related to the task structure of the software modules.
Page 99: Application Routines
Section 060-INDP-111 System Description 2-71 combined with a strong intercoupling of function modules. The BMC start- up and scheduler consists of six modules: • Process Scheduler • Clock Services • System Calls • Memory Manager • General Purpose Functions • Human-machine interface functions.
Page 100: Interface Routines
2-72 Section 060-INDP-111 System Description are provided to convert the raw data to the required format before processing any further. Other application routines manage events that must be scheduled on a regular basis. Call record report generation and BMC processor switchovers are two examples of the events directed by these application modules.
Page 101: Downloading Software To The Bmc
Downloading software to the BMC When a situation arises where the BMC requires a download of software, it is normally accomplished by transfer from an authorized source, usually Nortel. There are two possible BMC conditions that require the downloading of new software.
Page 102: Data Storage
2-74 Section 060-INDP-111 System Description Validated call records are loaded into a disk buffer on the SCSI Interface PCA, used for AMA call records. When a buffer is full, its contents are written to disk, while another buffer is made available to receive call records. Ribbon cables are used to send data and write commands from the SCSI Interface PCA to the SCSI Crossover PCA and both disk drives.
Page 103: Data Management
Section 060-INDP-111 System Description 2-75 command. For more information concerning the LSTDIR command, consult the Commands and Messages Guide section. The total number of ﬁles divides into two categories: dynamic and static. Dynamic ﬁles are usually large, while most static ﬁles are small. Most dynamic ﬁles are data ﬁles consisting of AMA and log (LOG) records.
Page 104: Block Types
2-76 Section 060-INDP-111 System Description Generally, call record data blocks from the Switching System are formatted as LSSGR data blocks. Other ﬁles on disk contain the site data and statistics. An Error Block is generated and used during ﬁle transfer to the HOC to indicate that a data block could not be successfully read from the storage device.

The second interface also returns an EOT to the Switching System and a critical alarm is generated. When the allocated disk space for AMA ﬁles is reached, the following actions occur: 1.
Page 107: Bad Track Mapping
Section 060-INDP-111 System Description 2-79 In the extreme case, where the second disk reaches 100 percent usage, the following activities occur: 1. Alarm level is raised to critical. 2. BMC returns EOT status to the Switching System. 3. Switching System transfers to the second interface. 4.

The headers and trailers are generated and maintained by the BMC. Other ﬁles handled by the BMC include: statistical, error, communication, and security ﬁles.
Page 109: Bisync Station Modes
Section 060-INDP-111 System Description 2-81 There are basically two types of messages in the BISYNC protocol: Text and Control. Control messages are used to administer the link. These messages are also referred to as "overhead." Text messages contain the information that the application programs exchange.
Page 110: Message Transmission
2-82 Section 060-INDP-111 System Description • EOT - used to indicate the end of application information. • Acknowledge (ACKn - n = 0 or 1) - used to accept the last message received. The ACK0 and ACK1 messages are generally alternated. •...
Page 111 Section 060-INDP-111 System Description 2-83 • ACK0 message - sent in response to an ENQ message after entering Listener mode. • NAK message - sent in response to an ENQ message if the station is unable to enter Listener mode. Both stations, while in Contention mode, can attempt to enter Talker mode by sending an ENQ message.
Page 112: Structure Identifier
2-84 Section 060-INDP-111 System Description • NAK message - indicates an unsuccessful reception of the last Text message. A re-transmission of that message is required. • RVI message - indicates successful reception of the last Text message plus a request to enter the Talker mode. The station in Talker mode should ﬁnish sending Text messages and then send an EOT message.

To provide greater understanding of operation, the transfer of data from the Switching System, the translation for intermediate storage, the polling of data to the HOC, and maintenance communications are described in this section.
Page 434 5-4 Section 060-INDP-510 System Operation Guide Note: TEC PCAs are found in BMC systems conﬁgured for use with DMS-10 Switching Systems. DSI PCAs are found in BMC systems conﬁgured for use with DMS-100 Switching Systems. BMC II System RAM When the Switching System transmits data blocks, a signal is sent to the active processor to accept the block.

All of these activities must be initiated by the HOC. BMC Communication The HOC initiates remote operation through a modem over either dial-up or dedicated lines.
Page 438 The second link provides maintenance access via SDI port (DMS-10 only). There is a third link on the Quad SIO PCA that is used for program download by Nortel. Like the modem links, the printer communication path connects the printer to the Power and Alarm Communications PCA before reaching the Quad SIO PCA.
