Channelized E1 Service - Lucent Technologies PortMaster 4 Configuration Manual

Configuring Channelized T1 or E1

Channelized E1 Service

Channelized E1 service is a digital standard used outside the United States. E1
technology is an improvement over T1 because it is slightly faster and contains
32 channels of 64Kbps capacity each. One channel is reserved for administrative uses,
and one channel is used for signaling.
Setting the In-Band Signaling Protocol for E1
Although PortMaster products do not require dial digits (the calling number and caller
ID) when establishing a connection, most telephone companies transmit this
information by default. You can use the r2generic signaling option if you do not
require dial digits, but you must first arrange for the telephone company to not transmit
these signals.
The PortMaster defaults to r2generic when you set the line to in-band (see
"Configuring Line Use" on page 10-5).
To accept caller ID and dial digit tones, use the mrf2 option. Because some countries
implement different variations of multifrequency robbed bit signaling (MFR2), you must
specify a profile with the mfr2 option.
To set the in-band signaling protocol and in-band call options for channelized E1, use
the following command. Table 10-13 explains the in-band signaling protocol options and
profiles.

Generic R2, the default; no caller ID and dial digit
tones are exchanged.
Accept caller ID and dial digit tones.
0 ITU standard; used in Argentina, Saudi Arabia, and
other countries. This is the default.
1 Mexico.
2 Brazil and Tunisia.
3 Venezuela.
4 Mexico. Profile 4 is a subset of profile 1 and is used
with switches that do not support caller ID. This
profile can be used in Mexico whenever profile 1 is
used, but the reverse is not true.
