Adding Channel Bridged E1 Ports

The channel bridged E1 ports are provisioned in the database using the ent-e1 command using these parameters.

:loc – The location of the E1 card (card type lime1) that is servicing the E1 signaling link. The E1 card must be an HC-MIM or an E5-E1T1 card. The location of a channel card (card type limch) cannot be specified for this parameter.

:e1port – The E1 port on the E1 card used to service the E1 signaling link. The e1port value cannot already be assigned to the E1 card specified by the loc parameter.

:crc4 – Specifies whether or not CRC4 is enabled on the E1 signaling link. The default value is on (crc4=on).

:cas – Specifies whether CAS or CCS is used on the E1 signaling link. CAS is enabled with the cas=on parameter. CCS is enabled with the cas=off parameter. The default value is CCS enabled (cas=off). The cas=on parameter cannot be specified for an HC-MIM or an E5-E1T1 card.

:encode – Specifies the type of encoding or decoding that is used on the E1 signaling link, either HDB3 or AMI. The default value is HDB3 encoding (encode=hdb3).

:e1tsel – The timing source for the E1 signaling link, master (external) or recovered. The default value is slave timing (e1tsel=line) which cannot be used for a channel bridged E1 port.

The recovered timing source can be used only with the chanbrdg=on parameter and uses the even numbered member of the bridged-pair as a clock source, ensuring that port in the pair can recover the timing from its partner.

Note:

To use an external high-speed master clock source other than RS-422, TDMs 870-0774-15 or later must be installed in card locations 1114 and 1116, and the TDM Global Timing Interface options must be configured. For more information, see Configuring the Options for the TDM Global Timing Interface.

:si – Specifies the value of the two spare international bits of NFAS data, from 0 to 3. The default value is 0 (si=0).

:sn – Specifies the value of the five spare national bits of NFAS data, from 0 to 31. The default value is 0 (sn=0).

:force=yes – Required when the even numbered E1 port being channel bridged is provisioned in the database before this procedure is performed.

:chanbrdg – Specifies whether or not the odd numbered E1 port specified in this procedure is channel bridged to its adjacent even numbered E1 port. Table A-9 shows the E1 ports that can be specified with the chanbrdg=on parameter and the even-numbered E1 ports that are bridged to the odd numbered E1 port.

Table A-9 Channel Bridging Ports

Odd Numbered E1 Port	Even Numbered Bridged E1 Port
1	2
3	4
5	6
7	8

The ent-e1 command contains the linkclass and minsurate parameters that are not used in this procedure. These parameters and their usage are described in Adding Unchannelized E1 Ports.

The E1 card specified in this procedure must be in the database. This can be verified with the rtrv-card command.

The E1 card cannot contain channelized and un-channelized E1 ports.

Display the cards in the EAGLE using the rtrv-card command.

Continue the procedure by performing one of these substeps.
1. If the rtrv-e1 output shows that the E1 card has E1 ports 3, 4, 5, 6, 7, or 8 assigned to it, or that E1 ports on the E1 card are channel bridged, continue this procedure with 3.
2. Channel bridged E1 ports cannot be added to an E1 card containing unchannelized E1 ports. If the E1 card contains unchannelized E1 ports, choose another E1 card from 1 and repeat this step, or add a new HC-MIM or an E5-E1T1 card by performing Adding a LIM-E1 Card.
3. If the rtrv-e1 output shows that the E1 card does not have E1 ports 3, 4, 5, 6, 7, or 8 assigned to it, or that E1 ports on the E1 card are not channel bridged, verify that the E1 card that the channel bridged E1 port will be assigned to is an HC-MIM or an E5-E1T1 card. The part number of the HC-MIM is 870-2671-XX. The part number of the E5-E1T1 is 870-1873-XX. If the E1 card is not an HC-MIM or an E5-E1T1 card, add a new HC-MIM or an E5-E1T1 card by performing Adding a LIM-E1 Card.
  - If an existing E1 card is being used in this procedure continue the procedure with 3.
  - If an HC-MIM or an E5-E1T1 card was added in this substep or substep b, continue the procedure by performing one of these steps.
    - If the E1 cards shown in this step are on the same shelf as the card that will contain the E1 port that is being added, and these cards have E1 ports 3 through 8 provisioned, contain channel bridged E1 ports, or unchannelized E1 ports, continue the procedure with 8.
    - If the E1 cards shown in this step are not on the same shelf as the card that will contain the E1 port that is being added, continue the procedure with 4.
    - If the E1 cards shown in this step are on the same shelf as the card that will contain the E1 port that is being added, and these cards do not have E1 ports 3 through 8 provisioned, do not contain channel bridged E1 ports, or do not have unchannelized E1 ports, continue the procedure with 4.

If an even numbered E1 port is to be channel bridged, and that E1 port is assigned to signaling links, these signaling links must be removed before the E1 port can be channel bridged. Perform Removing an SS7 Signaling Link and remove these signaling links. After the signaling links have been removed, continue the procedure with 4.

If the even numbered E1 port to be channel bridged is not assigned to signaling links, continue the procedure with 4.

Verify that HIPR2 cards are installed in card locations 9 and 10 in the shelf containing the HC MIM or E5-E1T1 card that will contain the E1 port being added in this procedure by entering this command.

Verify whether or not that the Fan feature is on, by entering the rtrv-feat command. If the Fan feature is on, the entry FAN = on appears in the rtrv-feat command output.

Note:
The rtrv-feat command output contains other fields that are not used by this procedure. If you wish to see all the fields displayed by the rtrv-feat command, see the rtrv-feat command description in Commands User's Guide.

If the Fan feature is on, continue the procedure with 8.

If the Fan feature is off, continue the procedure with Oracle.
Turn the Fan feature on by entering this command.
chg-feat:fan=on

Note:
Once the Fan feature is turned on with the chg-feat command, it cannot be turned off.
The Fan feature must be purchased before you turn this feature on with the chg-feat command. If you are not sure if you have purchased the Fan feature, contact your Oracle Sales Representative or Account Representative.

When the chg-feat has successfully completed, this message appears.

Add the new E1 interface information to the database using the ent-e1 command and the parameter combinations shown in Table A-10.

Table A-10 Channel Bridged E1 Port Combinations

Mandatory Parameters
:loc=location of the E1 card	:e1tsel=external, recovered
:e1port=1, 3, 5, 7	:chanbrdg=on
Optional Parameters
:cas=off Default value = off	:si=0 - 3 Default value = 0
:crc4=on, off Default value = on	:sn=0 - 31 Default value = 0
:encode=ami, hdb3 Default value = hdb3	:force=yes
Notes: 1. Channel cards cannot be specified with the `ent-e1` command. 2. To configure the E1 port for master timing, use the `e1tsel=external` parameter. 3. The `linkclass=chan` parameter configures a channelized E1 port. Specifying the `linkclass=chan` parameter in this procedure is unnecessary as this is the default value for the `linkclass` parameter. 4. The E1 card cannot contain channelized and un-channelized E1 ports. 5. The `force=yes` parameter must be used when the even numbered port being channel bridged is shown in the `rtrv-e1` output in 2 . If the even numbered port being channel bridged is not shown in the `rtrv-e1` output in 2 , the `force=yes` parameter cannot be used.

For this example, enter these commands.

ent-e1:loc=1301:e1port=1:encode=hdb3:e1tsel=external:si=1:sn=7:chanbrdg=on

ent-e1:loc=1303:e1port=1:crc4=on:encode=hdb3:e1tsel=recovered:chanbrdg=on
