The Cisco 8110 Broadband Network Termination Unit is a multiservice IP+ATM CPE device which enables service providers worldwide to cost effectively offer carrier class managed services to enterprise customers with high bandwidth needs and stringent service level agreements. The Cisco 8110 is optimized to enable a wide range of services including IP, ATM, Private Line, Voice and Video services over a single high-speed access link.
There are two methods of determining the 8110 Software Version:
In order to determine the Software Version, the system needs to be booted up. Following the boot up, the system will perform a serious of self tests . The Software Version is displayed at the end of the tests just before the Login prompt as shown in figure 1.

The Cisco 8110 will automatically switch between clock sources when a loss is detected on a specific interface. Cisco 8110 can use timing sources recovered from any one of the LIMs, external or internal clock. This recovered timing signal is used to generate the transmission clock.
Serial Line Internet Protocol (SLIP). Cisco 8110 permits remote access over a modem using the SLIP.
Cisco 8110 enables Packet InterNet Groper (PING), ICMP echo message and its reply to enable test reach ability of a network device.
Enable maintenance administration, can be used together with management application for Service Level Agreement Management (SLAM) and billing.
Script Function is used download or upload a script files using FTP protocol. Script files generated while uploading script are ASCII files that represent the command lines required setting the device to the state before uploading.
Software download via Ethernet or ATM interfaces, uses FTP or TFTP protocols.
PVC Bridging allows packets to be switched among PVCs. This feature is intended to support star topology in which all Cisco 8110s share one PVC with a central Cisco 8110. It is the responsibility of this central Cisco 8110 to perform the PVC bridging and therefore the network requires fewer PVCs. This results in a simpler and more economical network.
Switched Virtual Connection - A dynamically signaled logical end-to-end connection between two end-points in a network, established as needed by the end-user device.
Enables to create switched VCs and to maintain the connection open as long as it has not been closed by the user. From the user point of view it behaves as a permanent connection with auto recovery upon VC fault in the network.
Allows to translate the ATM cell header (change VPI/VCI) when switching a cell from port to port
Cisco 8110 has three LIM slots, It is possible to set mode of operation to two Network ports (In this mode each connection is assigned its Network port), two User ports (in this mode all connection are assigned to a single network port). Cisco 8110 can also operate in Automatic Protection switching (APS) enabling high availability scheme.
The capability to configure in one user command up to 1000 consecutive Ethernet Bridged VCsEncapsulation with its associated VCs.
Enable the network manager to easily view the provisioned connection QoS parameters in order to properly configure CSM CBR feature.
Cisco 8110 support Cisco 8100 EMS Management Software Application, a Client/Server architecture for Unix/NT platform. The Cisco 8100 EMS Features configuration, fault, performance and security management of the installed network devices. Based on HPOV, with Stand Alone and Web browser application.
Cisco 8110 can be used either as a fully remote management unit which uses in-band SNMP management through VCs, or a local out-band-management unit using a serial port. The manager can control the Cisco 8110, configure all the parameters, import usage parameters into billing application, read the status, performance and inventory information and perform preventive maintenance operations. Several password-protected levels of access are provided. Management can be established through Ethernet or ATM interfaces.
Cisco 8110 supports maintenance intensively. All maintenance indications are available locally by means of a serial channel or directly to the remote management. It includes alarms, performance monitoring, facility states, defects, loop back and more. External alarms are also supported to ease maintenance.
Cisco 8110 ATM LIMs has the option for Shaper. The shaper provides a mechanism for determining priorities between different classes of traffic. For example, class 0 can be defined to match CBR traffic and class 1 to VBR traffic. If the user defines class 0 with the highest priority, it will protect CBR traffic from unwanted discards due to bursty traffic on a LIM.
The 'group shaping' feature allows handling mixed types of traffic on the same VP. If for example the CES port is inactive all the bandwidth of the VP may be used for other, lower priority VCs.
When creating a virtual path, options may be used in combination with the required parameters for that path. Traffic shaping parameters define the negotiated traffic shape of a connection. The traffic shape refers to the load balancing of a network, i.e. configures the data flows to maximize the efficiency of the network. A Shaper can be assigned to egress or ingress path.
1. Cisco 8110 LIC - FE - Transparent LAN License for Ethernet/Fast Ethernet for the Cisco 8110
The Ethernet interface is either used as an Ethernet to ATM uplink or as Ethernet access to Management. The Ethernet supports auto negotiation 10/100 baseTx standards. There is no forwarding between the ports. The Ethernet interfaces support the relay layer of the IEEE 802.1 MAC Layer Bridge. Ethernet packets are bridged over ATM using RFC 1483, LLC for Bridging encapsulation. The bridge learns MAC addresses and forwards the required MAC addresses. Using Traffic Shaping, Per-Class-Queuing and Performance Monitoring, each LAN interconnection is assigned with required QoS and the performance of each connection is constantly monitored and measured End-to-End. Early Packet Discard mechanism yield an excellent goodput on the Ethernet uplink VCs.

The SNMP Cisco 8110 MIB is being provided with the delivery of Release 5.1c of the Cisco 8110 software on CCO. The MIB is in standard ASN.1 format and is located in the same directory within CCO. These files may be compiled with most standards-based MIB compilers. The following files are required:
When inserting / extracting LIM, it causes short period traffic interruption for the non-related traffic.
Partial fill range for UDT mode, is 33-47, it should be 24-47.
Activating CSM causes (due to the self test) other non-related traffic to loss cells.
Deployment of the 8110 system involves a configuration and installation process. Please refer to the User Manual (78-11666-01) for guidance. Updating software version from older version should be done according to the software download procedure. Updating not according to the procedure will result in unexpected behavior.
