Step Description Command Keys
4 Set the operation mode of the E1
interface.
esr(config-if-gi)# switchport mode
e1
5 Set the synchronization source
(optional).
esr(config-if-gi)# switchport e1
clock source <SOURCE>
<SOURCE> – synchronization
source:
Internal (default) –
synchronize with an
internal source;
line – synchronize with a
linear signal.
6 Specify MTU (Maximum Transmission
Unit) size for physical interfaces.
esr(config-if-gi)# mtu <MTU> <MTU> – MTU value, for E1 and
Multilink interfaces may take
values in the range of
[1510..9600].
7 Specify frame check hash algorithm
(optional).
esr(config-if-gi)# switchport e1
crc <FCS>
<FCS> – frame check
sequence:
16 (default) – FCS16;
32 – FCS32.
8 Set check for transmission errors
(optional).
esr(config-if-gi)# switchport e1
framing <CRC>
<CRC> – cyclic redundancy
check:
crc-4 – use CRC-4
algorithm;
no-crc4 (default) – do
not use check.
9 Set transmitting bits inversion
(optional).
esr(config-if-gi)# switchport e1
invert data
10 Set linear encoding type (optional). esr(config-if-gi)# switchport e1
linecode <CODE>
<CODE> – linear encoding type;
ami – alternatemark
inversion;
hdb3 (default) – high
density bipolar of order
3.
11 Set amount of timeslots. esr(config-if-gi)# switchport e1
timeslots <RANGE>
<RANGE> – amount of
timeslots.
12 Use E1 as a single entity, without time
slots (optional).
esr(config-if-gi)# switchport e1
unframed
E1 interface configuration:
13 Select E1 interface. esr(config)# interface e1 1/
<SLOT>/1
<SLOT> – slot number.
