Leasing E1 Timeslots
Leasing an entire E1 line is expensive and also a waste of the bandwidth resources. The private
line service leasing E1 timeslots can meet the requirement leasing a part of an E1 line. With this
service, users are assigned specific timeslots of an E1 line, and therefore can share the bandwidth
of the E1 line, hence saving the E1 line lease expense.

Context
The E1 private line service is mainly used in point-to-point (P2P) data exchange industries that
do not require immediate data exchange, such as finance, government, and enterprise. These
data exchange services do not need high bandwidth but have rigorous requirements on quality,
such as error code, delay, and packet loss. Leasing an entire E1 line is expensive and also a waste
of the bandwidth resources. The private line service leasing E1 timeslots can reduce costs and
improve bandwidth usage, which provides rates ranging from 64 kbit/s to 2 Mbit/s.
In this case, pay attention to the signaling mode of the E1 port. The signaling mode is set to be
common channel signaling (CCS) in general, which must be the same as that set on the peer
device in the digital data network (DDN).

Networking
Figure 4-9
The user end is connected to an SHDSL modem through a data terminal equipment (DTE) that
supports V.35 port, and then connected to the EDTB board of the MA5600T/MA5603T/
MA5608T through the TDM SHDSL port provided by the modem. By establishing internal SPCs
between different timeslots of the E1 and SHDSL ports, the EDTB board multiplexes timeslot
channels of different lines to the same E1 upstream port, implementing convergence of multiple
Nx64 kbit/s channels to the E1 port and saving E1 resources.

The H802EDTB board must be in position and must work in the normal state.
An SHDSL modem must be correctly connected and the SHDSL port must be activated.
CCS: frame format, in this mode, timeslot 0 is used to send frame synchronization
information and the other 31 timeslots are used to send valid data.
Use the existing rich twisted pair resources for long-distance transmission, extending the
DDN node.
The carrier does not need to deploy the new E1 line, which saves the deployment cost. The
user leases only one or more timeslots of the E1 line to save the lease expense.
