Ring Type—(Display only.) The default is two-fiber.
Speed—Choose the BLSR ring speed: OC-12, OC-48, or OC-192. The speed must match the OC-N
speed of the BLSR trunk (span) cards.
Note If you are creating an OC-12 BLSR and will eventually upgrade it to OC-48 or OC-192, use
the single-port OC-12 cards (OC12 IR/STM4 SH 1310, OC12 LR/STM4 SH 1310, or
OC12 LR/STM4 LH 1550).
Ring Name—Assign a ring name. The name can be from 1 to 6 characters in length. Any
alphanumeric string is permissible, and upper and lower case letters can be combined. Do not use
the character string "All" in either upper or lower case letters. This is a TL1 keyword and will be
rejected. Do not choose a name that is already assigned to another BLSR.
