1.2.2 Curbside Application
The IP DSLAM can also be used by an Internet Service Provider (ISP) in a street cabinet to
form a “mini POP (Point-of-Presence)” to provide broadband and phone services to residential
areas that are too far away from the ISP to avail of DSL or PSTN phone service. Residents
need an ADSL modem for data services, connected as shown in the previous figure.

- The ip dslam has two 1000 100mbps auto sensing ethernet ports there are two factors related to ethernet speed and duplex mode in 1000 100mbps fast ethernet the speed can be 100mbps or 1000mbps and the duplex mode can be half duplex or full duplex the auto negotiation capability makes one ethernet port able to negotiate with a peer automatically to obtain the connection speed and duplex mode that both ends support 48
- Use the ethernet ports for subtending you can daisy chain more ip dslam or other ethernet switches 48
- Ves 1624ft 55a user s guide 48
- When auto negotiation is turned on an ethernet port on the ip dslam negotiates with the peer automatically to determine the connection speed and duplex mode if the peer ethernet port does not support auto negotiation or turns off this feature the ip dslam determines the connection speed by detecting the signal on the cable and using half duplex mode when the ip dslam s auto negotiation is turned off an ethernet port uses the pre configured speed and duplex mode when making a connection thus requiring you to make sure that the settings of the peer ethernet port are the same in order to connect 48

- Configure a channel on the port for voice service set the channel to use the pvid of the static vlan you configured assign the channel a high priority 112
- Defining virtual channels also called permanent virtual circuits or pvcs allows you to set priorities for different services or subscribers you can define up to eight channels on each dsl port and use them for different services or levels of service you set the pvid that is assigned to untagged frames received on each channel you also set an ieee 802 p priority for each of the pvids in this way you can assign different priorities to different channels and consequently the services that get carried on them or the subscribers that use them 112
- For example you want to give high priority to voice service on one of the dsl ports 112

- Quality of service qos refers to both a network s ability to deliver data with minimum delay and the networking methods used to control the use of bandwidth without qos all traffic data is equally likely to be dropped when the network is congested this can cause a reduction in network performance and make the network inadequate for time critical application such as video on demand 119

- In stp once a stable network topology has been established all devices listen for hello bpdus transmitted from the root bridge if an stp aware device does not get a hello bpdu after a predefined interval max age the device assumes that the link to the root bridge is down this device then initiates negotiations with other devices to reconfigure the network to re establish a valid network topology 162
- Rstp assigns three port states to eliminate packet looping while stp assigns five see table 49 on page 162 a device port is not allowed to go directly from blocking state to forwarding state so as to eliminate transient loops 162

- As these two ip addresses cannot be used for individual hosts calculate the maximum number of possible hosts in a network as follows 245

- Since the mask is always a continuous number of ones beginning from the left followed by a continuous number of zeros for the remainder of the 32 bit mask you can simply specify the number of ones instead of writing the value of each octet this is usually specified by writing a followed by the number of bits in the mask after the address 245
