# path ds1|e1 channel-group timeslots

#### Syntax

path pathChannel { ds1 | e1 } tributaryIdentifier
channel-group channelGroupNumber timeslots range [ speed { 56 | 64 } ]

no pathChannel { ds1 | e1 } tributaryIdentifier channel-group channelGroupNumber

#### Release Information

Command introduced before JunosE Release 7.1.0.

#### Description

Configures DS1 or E1 line parameters on channelized SONET and SDH interfaces. To configure a line, you specify a DS1 or an E1 channel group number and assign a range of timeslots. To configure a whole DS1 or E1 line, assign all the timeslots to the channel group. You can specify a line speed that applies to all DS0 timeslots assigned to a channel group. The no version removes the timeslots from the channel group.

#### Options

- pathChannel—Number, in the range 1–2147483648, that identifies the path
- tributaryIdentifier—Specifier for the tributary in the format
  pathChannel { ds1 | e1 } pathPayload/tributaryGroup/tributaryNumber
  - pathPayload—Payload number for the path; value is 1 for SONET and in the range 1–3 for SDH
  - tributaryGroup—Number, in the range 1–7, that identifies the group within the path
  - tributaryNumber—Number of the tributary within the tributary group; the value is in the range 1–4 if the tributary type is vt15 or tu11 and in the range 1–3 if the tributary type is tu12
- channelGroupNumber—Either a fractional T1 interface in the range 1–24 or a fractional E1 interface in the range 1–31
- range—Timeslot assigned to the T1 or E1 channel in the range 1–31. A dash represents a range of timeslots, and a comma separates timeslots. For example, 1-10, 15-18 assigns timeslots 1–10 and 15 –18.
- speed—Specifies the data rate for the T1 or E1 channel, either 56 Kbps or 64 Kbps; default value is 64 Kbps
