The 1-Port Channelized STS-1e, T1 format module provides one port with a
line rate of 51.84 Mbps. The user can configure this module to provide
n X 64 Kbps (fractional DS1) structured circuit-emulation service. When
configured for DS1 circuit-emulation service, the module interfaces with
TDM channelized DS1 circuits. It converts the channelized digital signals
(usually voice data) to ATM virtual channels. By using structured
(channelized) circuit emulation, the 1-Port Channelized STS-1e, T1 format
module can adapt a maximum of 28 DS1 channels per port to ATM virtual
channels with individual VPIs and VCIs. Signaling bit transport is also
provided, using ATM Forum standards for channel-associated signaling
(CAS). This module can connect to a device using 56 Kbps or 64 Kbps for
service transport, with 8 Kbps for robbed-bit signaling per DS0. With the
64 Kbps "clear channel" capability, this module can connect to a device using
ISDN primary rate interface (PRI) service. Because this structured circuit-
emulation service can be configured to use only a fraction of the time slots,
the user can configure several independent emulated circuits to share one
service interface.
The 1-Port Channelized STS-1e, T1 format module uses ATM Forum
specifications UNI 3.0 or UNI 3.1, which allow any DS1 port to act as a user
network interface (UNI), or an interim interswitch protocol (IISP) user or
IISP network interface to an ATM network.
