6.2.2Virtual Channel Cross Connect Group (RFC 2515)

This table contains configuration and state information of point-to-point, point-to-multipoint or multipoint-to-multipoint VC cross-connects for PVCs. This table has read-create access and is used to cross-connect the VCLs together in an ATM switch or network that belong to a VC connection. The atmVcCrossConnectIndex is used to associate the related VCLs that are cross-connected together. The model using step-wise procedures described for setting up a VP cross-connect is also used for setting up a VC cross-connect. The ATM Virtual Channel (VC) Cross Connect Table, atmVcCrossConnectEntry table contains the following objects:

6.2.3“atmVcCrossConnectL2HOperStatus” Object (atmVcCrossConnectEntry 9)

The value of this object identifies the current operational status of the VC cross-connect in one direction; (that is, from the low to high direction). The up and down states indicate that this ATM VC cross-connect from low to high direction is operational or not operational respectively. The unknown state indicates that the state of it cannot be determined. The only valid values for this object are:

up(1)

down(2)

unknown (3) (NOT_SUPPORTED)

6.2.4“atmVcCrossConnectH2LOperStatus” Object (atmVcCrossConnectEntry 10)

The value of this object identifies the current operational status of the VC cross-connect in one direction; (that is, from the high to low direction). The up and down states indicate that this ATM VC cross-connect from high to low direction is operational or not operational respectively. The unknown state indicates that the state of it cannot be determined. The only valid values for this object are:

up(1)

down(2)

unknown (3) (NOT_SUPPORTED)

6.2.5“atmVcCrossConnectL2HLastChange” Object (atmVcCrossConnectEntry 11)

The value of MIB II’s sysUpTime object at the time this VC cross-connect entered its current operational state in low to high direction. If the current state was entered prior to the last re-initialization of the agent, then this object contains a zero value.

6.2.6“atmVcCrossConnectH2LLastChange” Object (atmVcCrossConnectEntry 12)

The value of MIB II’s sysUpTime object at the time this VC cross-connect entered its current operational state in low to high direction. If the current state was entered prior to the last re-initialization of the agent, then this object contains a zero value.

6.2.7“atmVcCrossConnectRowStatus” Object (atmVcCrossConnectEntry 13)

The status of this entry in the atmVcCrossConnectTable. This object is used to create a new cross-connect row for cross-connecting VCLs which are created using the atmVclTable or to change or delete existing cross-connect. This object must be initially set to ‘createAndWait’ or ’createAndGo’. This object cannot be set to ‘active’ unless the following columnar object exists in this row: atmVcCrossConnectAdminStatus. To turn on a VC cross-connect, the atmVcCrossConnectAdminStatus is set to ‘up’. The only valid values for this object are:

8620, 8820 specifications

The Paradyne 8620 and Hotwire 8620 GranDSLAM are advanced DSLAM devices designed to provide high-speed broadband access over existing copper lines. This installation guide will outline the main features, technologies, and characteristics of these powerful units.

The Paradyne 8620 is engineered to support various DSL technologies, including ADSL, ADSL2+, and VDSL. This versatility allows operators to deploy services tailored to the needs of their customers, enabling data rates of up to 50 Mbps downstream, making it an ideal choice for meeting increasing bandwidth demands. The Hotwire 8620 GranDSLAM shares many similarities, focusing on providing enhanced service delivery for both residential and business users.

One of the key features of the GranDSLAM series is its modular architecture. Both models support up to 48 subscriber line interfaces in a single chassis, which provides significant scalability. Operators can seamlessly increase capacity by adding additional cards to accommodate growth. The devices are designed for easy deployment and management, equipped with an intuitive web-based interface that simplifies configuration and monitoring tasks.

Both units also feature advanced management capabilities, including support for SNMP and TR-069 protocols. This allows service providers to manage and provision devices remotely, significantly reducing operational costs and improving service reliability. The GranDSLAM models can also provide detailed diagnostic information, helping operators quickly identify and troubleshoot issues.

The Paradyne and Hotwire series ensure interoperability with various customer premises equipment, enabling service providers to offer bundled services such as voice, video, and data over the same connection. This capability is enhanced by the units’ ability to support VLANs and QoS features, ensuring that high-priority traffic receives the necessary bandwidth.

In addition to performance, the 8620 series is built with energy efficiency in mind. By utilizing power-saving features, these units help reduce overall operational costs while still providing reliable service.

Overall, the Paradyne 8620 and Hotwire 8620 GranDSLAM are robust solutions for service providers looking to deliver high-speed broadband services. Their modular design, advanced management capabilities, and support for multiple DSL technologies make them an excellent choice for today’s demanding telecommunications environment. With these advantages, operators can effectively meet customer needs while preparing for future growth and technology advancements.
