Configuring E1 Interfaces

This chapter describes how to configure E1 interfaces and the supported options. E1 interface configuration maintains a 1-to-1 relationship between the line interface unit (LIU) ports on the Cisco Optical Networking System (ONS) 15304 and the VC-12s. As a result, both the LIU ports and their corresponding VC-12s should be created prior to cross-connecting them. This chapter covers the ine enter/edit/delete E1 set of commands.

The Cisco ONS 15304 E1 interface is a transparent interface providing the ability to cross-connect any E1 service to a VC-12. This allows the Cisco ONS 15304 to pass traditional voice traffic as well as video and data traffic. As a result, the Cisco ONS 15304 can transport not only traditional voice traffic but also ATM and IP traffic.

Configuring E1 Physical Ports

The E1 ports are configured using the Cisco ONS 15304 ine enter command. To configure the E1 ports, complete the following steps:

Task

Command

Access the config mode.

ONS# configure terminal

Place the E1 port in-service. For descriptions on other available options, refer to "Commands for E1 Ports" on.
Note If no framing type is specified, unframed will be used.
ONS (config)# ine enter e1 admin is

Repeat these two tasks for each E1 port.

Task	Command
Access the config mode.	ONS# configure terminal
Place the E1 port in-service. For descriptions on other available options, refer to "Commands for E1 Ports" on. Note If no framing type is specified, unframed will be used.	ONS (config)# ine enter e1 admin is
Repeat these two tasks for each E1 port.

Commands for E1 Ports

ine enter e1---To configure the specified E1, use the ine enter e1 configuration command. The configurable parameters are listed below.

(config)#ine enter e1 e1-range
[fac-id string] 
[framing {cept-no-crc | cept-crc4 | unframed}] 
[fm-rept {on | off}]
[almpfl profile-number] 
[tca-rept {on | off}] 
[gos 1]
[delay date time] 
[trig time] 
[admin {is | oos}] 
[timing transparent]

[ts16 {data | Signal}]

Parameter Description

e1

E1 port. The field e1-range can be a single number in the range 1 to 8 OR a combination of numbers in the range 1 to 8 delineated by commas, (for example 3,5,7) OR a range of numbers in the range 1 to 8 (for example 3-7). Therefore, the choices for the field <e1-range> are <1-8> or <1-8>,<1-8>... or <1-8>-<1-8>.

fac-id

Facility id is the user-entered field that is used to easily identify an E1 interface. The facility id is an alphanumeric string that can be up to 64 characters long.

framing

Framing indicates the type of framing used for the E1 interface. Framing is either CEPT or unframed when no framing is needed. Framing can be either CRC4 (cept-crc4) or no CRC (cept-no-crc).

fm-rept

Fault monitoring reporting setting. Select on if all fault conditions on the E1 should be reported (that is alarms should be declared). Select off if all fault conditions on the E1 should not be reported. Default setting is on.

almpfl

Index of the alarm profile that should be used for this E1. The choices are 1, 2, 3, 4 (which are user specified alarm profiles), std and not-reported (that is all the alarms have severity set to Not Reported [NR]).

tca-rept

Threshold Crossing Alert (TCA) reporting flag. Select on if all TCAs on the E1 should be reported. Select off if all threshold crossing alerts on the E1 should not be reported. Default setting is on.

gos

Index of the Grade of Service (GOS) profile to be used for this E1. The GOS profile contains the thresholds for threshold crossing alerts (TCAs). The choice for gos is currently only 1.

delay

Auto delay time allows operators to inhibit TCA reporting and fm reporting (that is alarm declaration) on the E1 up to a specified date and time. This feature is useful when the remote end or intermediate facilities have a known outage time or while troubleshooting the network. It is also useful while setting up new facilities when the remote end has not yet been set up. The maximum auto delay time is 90 days. The date parameter has to be entered in the mm/dd/yyyy format and the time parameter has to be entered in the hh:mm format. Default value is 00/00/0000 00:00.

trig

Auto trigger timer allows operators to set a trigger timer that can last for up to 23:59 hours. The time parameter, which is in the hh:mm format, indicates the time for which the E1 has to be continuously functional before threshold crossing alert (TCA) reporting and fm reporting are activated. The auto trigger timer is set for the specified value when the E1 comes up. If the E1 goes down before the auto trigger timer is triggered, the auto trigger timer is reset to the specified value. When the auto trigger timer is triggered, TCA reporting and fm reporting are activated (if tca-rept and fm-rept are set to on) and the configuration value of trig is changed to zero. This feature is useful when the facility is known to have some irregularities in the early part of its being up. Default value is 00:00.

admin

Administrative state. Select is to place the E1 in service. Select oos to place the E1 out of service.

timing

Transmit timing mode. Select transparent when the timing for the E1 is passed through. Select system when the transmit timing for the E1 is derived from the system clock. Note that transparent timing can be selected on all the E1s (8). Check under modifications.

ts16

Indicates whether timeslot 16 should be used either for data or signaling purposes.
