Channelized T1, E1 and T3 Services Overview WAN Configuration
Basic Channelized T1, E1 and T3 Interface Functions
MLPs
Multilink PPP (MLPs) is a set of multiple physical links grouped into a logical pipe called an MLP bundle.
Channelized T1 and E1 MLPs can be used for splitting, recombining and sequencing datagrams. Create a MLP with
Channelized T1 lines using the following commands.
For the MLP example:
• ppp create-mlp mp.1
- Creates a multilink PPP bundle named mp.1.
• slot 2
- Designates the MLP slot number.
• ppp add-to-mlp mp.1
- Adds ports to a previously defined bundle mp.1.
• port t1.2.(1-4)
- Designates the ports to be added to the bundle.
Note
MLP bundles cannot be created across multiple line cards.
VLANs
Channelized T1 or E1 VLANs can be created and used for bridging to MSP’s. Create a VLAN using the following
command.
For the VLAN example:
• vlan create vlan1 port-based
- Creates a port-based VLAN.
• id 100
- Names the VLAN.
T1 Lines
T1 lines (channels) can be created within the Channelized T3 interface. Channelized T3 interfaces with T1 lines can
be used for multimedia transmission within one Channelized T3 interface. Create T1 lines for a Channelized T3
interface using the following commands.
For the T1 lines example:
• port set t3.4.1:(1-28)
- Configures the following parameters for all 28 T1 lines of the
Channelized T3 interface on port 1.
• timeslots 1-24
- Sets the range of time slots, on the T1 lines to select in a frame, from 1 to 24.
• wan-encapsulation ppp
- Sets the WAN encapsulation type to PPP. This must be specified on
the same line as the timeslots.
