Adding Channelized and non-Channel Bridged T1 Ports

The channelized and non-channel bridged T1 ports are provisioned in the database using the ent-t1 command using these parameters.

:loc – The location of the T1 card (card type limt1) that is servicing the T1 signaling link. The location of a channel card (card type limch) cannot be specified for this parameter.

:t1port – The T1 port on the T1 card used to service the T1 signaling link. The t1port value cannot already be assigned to the T1 card specified by the loc parameter.

:encode – Specifies the type of encoding or decoding that is used on the T1 signaling link, either B8ZS or AMI. The default value is B8ZS encoding (encode=b8zs).

:t1tsel – The timing source for the T1 signaling link, master (external), slave (line), or recovered. The default value is slave timing (t1tsel=line).

The recovered timing source can be used only with the chanbrdg=on parameter and cannot be used in this procedure.

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, refer to Configuring the Options for the TDM Global Timing Interface.

:framing – Specifies the framing format to be used on the TI signaling link, either sf or esf. The default value is sf (framing=sf).

:ll – The length of the cable, in feet, used for the T1 signaling link. The value of the ll parameter is from 0 to 655. The default value for this parameter is 133.

The ent-t1 command contains other parameters that are not used in this procedure. These parameters and their usage are described in these sections:

t1tsel=recovered, chanbrdg, and force=yes – Adding Channel Bridged T1 Ports.
framing=esfperf, linkclass, and minsurate – Adding Unchannelized T1 Ports.

The T1 card specified in this procedure must be in the database. This can be verified with the rtrv-card command.

The T1 card cannot contain channelized and unchannelized T1 ports.

Display the existing T1 interfaces in the database using the rtrv-t1 command with no parameters.

Continue the procedure by performing one of these substeps.

If the T1 card that the T1 port is being assigned to in this procedure is not shown in the rtrv-t1 output, or if the T1 card has unchannelized T1 ports assigned to it, continue the procedure with 2 to verify if there are any T1 cards in the database that have no T1 ports assigned to them.
If the rtrv-t1 output shows that the T1 card has channel bridged T1 ports assigned to it, or that T1 ports 3, 4, 5, 6, 7, or 8 are assigned to the T1 card, the T1 card is an HC-MIM or an E5-E1T1 card. Continue the procedure with 7 to add the T1 port with the parameters allowed for an HC-MIM or an E5-E1T1 card.
If the rtrv-t1 output shows that the T1 card does not have channel bridged T1 ports assigned to it, or that T1 ports 3, 4, 5, 6, 7, or 8 are not assigned to the T1 card, verify the type of T1 card that the T1 port will be assigned to. The T1 card types and their part numbers are shown in Table B-4. If the T1 card is an HC-MIM or an E5-E1T1 card, continue the procedure by performing one of these steps.
- If the T1 cards shown in this step are on the same shelf as the card that will contain the T1 port that is being added, and these cards have T1 ports 3 through 8 provisioned, contain channel bridged T1 ports, or unchannelized T1 ports, continue the procedure with 7.
- If the T1 cards shown in this step are not on the same shelf as the card that will contain the T1 port that is being added, continue the procedure with 3.
- If the T1 cards shown in this step are on the same shelf as the card that will contain the T1 port that is being added, and these cards do not have T1 ports 3 through 8 provisioned, do not contain channel bridged T1 ports, or do not have unchannelized T1 ports, continue the procedure with 3.

If the T1 card you wish to use in this procedure has all the T1 ports that are allowed to be assigned to it, select another T1 card to add the T1 port to, or continue the procedure with 2 to verify if there are any T1 cards in the database that have no T1 ports assigned to them. Table B-7 shows the number of T1 ports that are allowed for the different T1 card types.

T1 Card Types	Maximum Number of T1 Ports
HC-MIM	8
E5-E1T1	8

Continue the procedure by performing one of these substeps.
1. If the desired T1 card is not shown in the rtrv-card output, perform Adding a LIM-T1 Card to add the desired T1 card. If you wish to assign T1 ports 3, 4, 5, 6, 7, or 8 to the T1 card, the T1 card being added must be an HC-MIM or an E5-T1T1 card.
2. If the desired T1 card is shown in the rtrv-card output, verify the type of T1 card that the T1 port will be assigned to. The T1 card types and their part numbers are shown in Table B-4.
3. If the T1 card that will be used in this procedure is an HC-MIM or an E5-E1T1 card, continue the procedure by performing one of these steps.
  - If T1 cards are shown in 1 that are on the same shelf as the card that will contain the T1 port that is being added, and these cards have T1 ports 3 through 8 provisioned, contain channel bridged T1 ports, or unchannelized T1 ports, continue the procedure with 7 to add the T1 port with the parameters allowed for an HC-MIM or an E5-E1T1 card.
  - If no T1 cards, shown in 1, are not on the same shelf as the card that will contain the T1 port that is being added, continue the procedure with 3.
  - If T1 cards are shown in 1 that are on the same shelf as the card that will contain the T1 port that is being added, and these cards do not have T1 ports 3 through 8 provisioned, do not contain channel bridged T1 ports, or do not have unchannelized T1 ports, continue the procedure with 3.
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 T1 port being added in this procedure by entering this command.

If HIPR2 cards are installed in the shelf containing the HC MIM or E5-E1T1 card, continue the procedure by performing one of these steps.
- If the card is an E5-E1T1 card, continue the procedure with 7.
- If the card is an HC MIM, continue the procedure with 4.
If HIPR2 cards are not installed on the shelf containing the HC MIM or E5-E1T1 card, go to Installation User's Guide and install the HIPR2 cards. Once the HIPR2 cards have been installed, continue the procedure by performing one of these steps.
- If the card is an E5-E1T1 card, continue the procedure with 7.
- If the card is an HC MIM, continue the procedure with 4.
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 7.

If the Fan feature is off, continue the procedure with 5.
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 Sales Representative or Account Representative.
The shelf containing the HC-MIM being added in this procedure must have fans installed. Verify whether or not fans are installed on the shelf.

If the fans are installed, continue the procedure with 7.

If the fans are not installed on the shelf containing the HC-MIM, go to Installation User's Guide and install the fans. After the fans have been installed and tested, continue the procedure with 7.

Add the new T1 interface information to the database using the ent-t1 command and the parameter combinations shown in Table B-8, based on the type of T1 card being used.

Table B-8 T1 Interface Parameter Combinations

HC-MIM or an E5-E1T1 Card without Channel Bridging
Mandatory Parameters
:loc=location of the T1 card
:t1port=1, 2, 3, 4, 5, 6, 7, 8
Optional Parameters
:encode=ami, b8zs Default value = b8zs
:framing=sf, esf Default value = sf
:ll=0 - 655 Default value = 133
:t1tsel=line, external Default value = line
Notes: 1. Channel cards cannot be specified with the `ent-t1` command. 2. To configure the T1 port for master timing, use the `t1tsel=external` parameter. 3. The `linkclass=chan` parameter configures a channelized T1 port. Specifying the `linkclass=chan` parameter in this procedure is unnecessary as this is the default value for the `linkclass` parameter.

For this example, enter these commands.

ent-t1:loc=1215:t1port=2:encode=b8zs:t1tsel=line:framing=sf:ll=100

Verify the changes using the rtrv-t1 command specifying the card location and the t1port value specified in 7. For this example, enter this command.
