Analog and digital trunks
Wave supports both analog and digital trunks. Your central office provisions each of your trunks
for specific handshake and signaling options, which they provide in your Service Confirmation
Letter (see , Service Confirmation Letters and Provisioning Information Forms). You must enter
these values in Wave for the trunks to operate properly with the equipment on the
service-provider end of each trunk.
Before you configure trunks, ensure that your trunk groups are configured appropriately. For
more information about trunk groups, see “Trunk groups” on page 27-4. For trunk group
configuration procedures, see “About creating new trunk groups” on page 5-2.
Analog trunks
The Integrated Services Card in your Wave Server provides 4 analog trunk ports. Additional
analog trunk ports may be available if one or more modules that provide analog trunk ports
(Analog Trunk Module or Analog Universal Module) are installed on your Wave Server. Each
trunk can carry a single voice call or a single 56 Kbps modem data call.
Note: The Wave Server supports one 56 Kb modem call using the internal modem on the
Integrated Services Card. You can connect additional modems externally to analog station ports.
For trunk configuration procedures, see “Configuring trunks and channels” on page 5-13
Digital trunks
The Wave Server supports the following digital connections:
•
T-1. Transports a stream of Digital Signal 1 (DS1) frames. Each frame transports up to 24
channels of traffic, with each channel supporting a single voice call or 56/64 kilobits (Kb)
of data traffic. You can configure each of the 24 channels of the T-1 connection
independently to transmit voice or data.
The Wave Server supports data connections up to 1.544 Megabits per second (Mbps) and
can switch voice and data traffic from four T-1 connections simultaneously.
For T-1 configuration procedures, see “Configuring digital trunks and channels” on
page 5-21.
